RE: Captcha the Bots! - Alblaka - 01-12-2010
Actually i don't like any kind of captcha method since they tend to be a challenge to read. Additional, often i encountered "Capital letters are not required" (or however its in english) though you actually need to differ between capital and usual letters...
I'm fine with anything but captcha... though... i actually dont need to register here anyways (anymore) XD
RE: Captcha the Bots! - Simoneon - 01-12-2010
The best part is that they have the same ip.
Actually they all had a link at their signature before, and that previous bot didn't. That made me really confused, because, well, looking at his ip: there was nobody found. So yea, I don't have very big arguments - I could've banned a human
There was captcha before new years, and long time they didn't register. Except the bot after new year...
Maybe they've created new bot tipe, after new years? Anyone agree?

I just state, that a couple of O,o,0 and 8 could may be mistaken when they cross each other, additionally rotated by 90 degrees sometimes...
Btw, what is the meaning of "sceneries"?

I just looked at our captcha... It looks easy to OCR. I wouldn't be surprised if they had OCR functions designed especially for captcha purposes.

You have three pictures with radiobuttons below them: a desert, an aeroplane and a waterfall.
The instruction would be "Select the picture with the aeroplane."
I don't think bots could OCR those.
RE: Captcha the Bots! - MH-Razen - 01-12-2010
actually creating captchas is highly advanced PHP stuff - it requires a lot of experience to do something like that. This is why there`re only a few good captcha-systems - we use this one: http://recaptcha.net/
Not sure, but should be good enough. I`m not sure when these bots you talk about now registered, if they regstered in the last few weeks we still have to worry...
RE: Captcha the Bots! - blow_fly98 - 01-13-2010
I think simo told me the last bot registered after new years.
And anyway, I'm positive that a captcha with pictures (not words) is probably as easy as our LFE ad thing and also easier than our current captcha system. And I'm probably wrong as I don't know PHP.

- CAPTCHA ~ is there
- CAPTCHA but not with words ~ is there
- Some general knowledge question about Little Fighter 2 ~ as MH said, captchas are advanced stuff, so I fear that this option will vanish out.
So far, there are 32 bots on our black list. So don't think that there are just a few...
By the way, it seems that there are occasional bot-floodings. A couple weeks ago, there wasn't only the bot-flood on LFE but also on 4chan. I can imagine that a bunch of other sites were affected. So this seems to be a global problem.
There's just one thing for sure: if you see a thread titled with "Your favorite xyz", be cautious. It is better to directly report the thread than answering those posts. Let the threads die / disposed.
RE: Captcha the Bots! - MH-Razen - 04-06-2010
well, as far as I can see we still have the bot problem - tell me if I`m wrong.
I browsed several other forums and saw that they use questions - like "who`s the creator of LF2" (in our cases) - I think of adding one question like this in case I find a quick plugin for this - if one of the guys out there wanna help with the search:
we`re using Mybb 1.4
