View Full Version : Spam reduced or eliminated? I think so.

It seems that many of the outright spam and nonsense posts have been eliminated. I am sure that is because of the new system for registration. New members have to go through some sort of approval process - which I have no information on. I don't have the authority to approve new members - but I can ban them (YEAH!)

At the very bottom of the main forum page, you can find a link to see who is online and where they're browsing. As a super-moderator, I can see that it is usual to have 30% of the unregistered guests being blocked as they try to post, start threads, and create events, etc. They are blocked and meet with a permission denied message.

I have been banning users that have a low or zero post count, with oddities such as saying they reside in "uk" but have an IP address in India or China and their time zone set to the middle of the Pacific. Usually their bio says "Man" or "1". I copy their IP Address and do a search on them. Usually, they turn up listed in anti-spam sites, and I found a website that shows were the IP address is physically located (supposedly). I searched my own IP, and a few other trusted members' IP addresses, and as expected, they did not show up in anti-spam lists, and the locations made sense for the members' locations.

A lot of these banned users still lurk in the forums, reading ancient threads or trying to post. Some members write some very weird posts, and it is hard to tell if they are just bad at writing in English (it happens), or if it is some sort of content spammer software automatically generating somewhat topical gibberish. I am suspect of a few members like this. I am afraid that some day, our suspect member will have 50 odd posts all over this forum, then change their signature with some outright spam or URL links. I think the goal of some spammers is to see how many links they can have on pages all over the internet. Somehow, this works to their advantage, but it certainly doesn't help us.

I noticed a lot of banned users or unregistered guests viewing threads about big zoom lenses like 120-600 monsters. It seems they stay on those pages for hours or days. Weird.

It seems there is almost ALWAYs a Google Spider in here reading. I even found it reading a page that listed all the members' birthdays for a particular day in the year 2011. I copied a unique line off that page, and put it in a Google search, and our Forum page came up instantly. It's almost creepy. You should know that everything you write will be Google-spidered into some database. I've also seen "Ask Jeeves" spiders and bots grinding through our pages.

Tom,

Once again, I'd just like to thank yourself, Blackjack, Ol'Coot and the generic looking Swampguest for the time you're all putting in to blocking and weeding out the spam.

Whilst the irritating posts aren't generally dangerous or detract from the 'family friendly' status of this forum they do, as I'm sure they're intended to, throw you when reading a thread.

In this ever increasingly noisy and malevolent world, it becomes more difficult to keep the chaos at bay but to answer your question - yes, I feel the spam level has gone down dramatically :righton:

Thank you.

Keith.

I just saw that we now have about 204 banned users. I think there's 100 names per page on the list, and we've started a 3rd page.

I wonder about doing a purge to eliminate the approx 330 members that joined over a year ago and never posted.

Great job Tom ! I'll second the others: the spam "seems" to have reduced ! ...but "one" must stay vigilant, as the blØØdy spammers will surely discover ways to get thru :mad2: !

Good idea too to eliminate the "useless" and "non-productive" would-be members who signed-in more than one year ago and only posted once...

...as the REAL "old" members seem to fade away... we would en-up with more spammers than active people :woot: !

:clap:
J-P.

the "newest" trick appears to be posting a handful of "beginners" like posts without a spam signature to establish oneself, and THEN after a month or so changing to a spam link signature - there's at least one up right now as I type this.

I agree. This clown's posts were almost on-topic for the most part, but I was suspicious. I actually thought I had banned him already, but maybe I gave him the benefit of doubt. He is banned now, and I deleted all his posts. His claimed location did not match with his IP location.

So, now that it's harder for spammer to get in here, it's also harder for legit new members to get in here. They have to be approved by some moderator (I don't have that power) before they can contribute or we can view their profile. I think the last member that got in was on Nov 6th, and everyone since is still locked out. I think the current backlog is about 7 people waiting.

If you're one of those waiting to get in, I am working on getting you in.

One new member is still waiting to get in is me, as a guest, as a test, (Tom V Guest) just to see how long this is going to take.

I noticed a lot of banned users or unregistered guests viewing threads about big zoom lenses like 120-600 monsters. It seems they stay on those pages for hours or days. Weird....

I just looked to see who was viewing what. Currently, two (2!) guests are reading a thread titled "Nikon 1000mm ED F/11. Any comments?" I have to wonder "why?" One viewer's IP is from Australia and the other is from California.

Another commonly viewed thread is one I wrote about a camera stand.

The banned user list is up to 317.

I have changed the user registration method for a third time. Trying to find what is the best way to allow users to register while still spotting spammers.

It is a work in progress

Good luck guys. Now you know how legislatures feel, make new rules and someone(s) always finds the loop hole or weakest link.

Keep up the good work.
