IP/Spam Filters? Captcha?

Postby Synchronicity » Wed Dec 19, 2012 10:27 am

This is absurd. We're getting the same one kind of spammer out of Russia who posts literal gibberish mixed with random links. Every time I log in to Space Potatoes there's at least four of them at any one time that I need to clear out. Is there anyway we can strengthen the anti-bot measures when you register or just flat-out filter some of the IPs coming out of Russia? I know there are lists full of spam filters we could accurately use without stopping anyone legitimate from joining.

I'll look into it further. The problem is the accounts all have gmail addresses. Which I think means it likely isn't a bot but some people that are spamming this stuff. I'll see what I can come up with to combat this further however.

You could have it ask a simple question that a computer can't answer. They also have picture captcha, where it'll have a small pic of a house or a guitar or something, and the person types in what they see.

The obvious fix is to disable creation of threads by new users. At least that will make them change up their spamming strategy. Make an "Introduce Yourself" sticky and/or Q&A thread if you're worried about real people coming in and wanting to create one right away.

I've never liked that tactic as it only works to dissuade people from signing up and sticking with the community. I have a good idea for the fix, I just haven't had time to implement it yet. I will likely be doing a full maintenance on the forums probably next weekend and will be able to put the new security in place at that time.

Just saw our first spammer of the new year! What else have you got up your sleeve? ;)

^ They were probably already registered.

No they weren't already registered. I really think we are dealing with a person spamming. Which means automated tools aren't going to stop them. I may have to upload a blacklist mod that blocks known ranges of IPs of spammers. We'll monitor things for a few weeks/months (depending on how bad it gets) and see what we need to do.

Yeah I've noticed, been very calm so far. We'll keep an eye on things.
