The spam bots have learned to solve simple mathematical captchas like 1*2+3*4/6-5.

I suggest using ReCaptcha instead, as it's stronger and harder to recognize by algorithms.

There is already a reCaptcha but the spammers are either using humans to solve them or AI. Usually I just need to change the questions a little bit and the spammers stop getting in for a few months until they update their bots...

Yeah, nowadays many spammers are registered manually. Probably by people from third-world countries being paid $30 per day to do it.

 

Also I tried reCaptcha in the past and removed it from my site, because when reCaptcha servers were down or slow, it prevented the rest of the registration page from loading. I heard they were bought by Google a few years ago, though, so maybe that improved? But yeah, that won't stop manually registered spam accounts from going in.

 

Something I found effective, though, is to disallow 0-post members from posting web links. They just have to edit the link in after they made the post, but that might be annoying to some new members I guess.

You may have added an extra zero there cause that's an insanely good salary for the third world. https://en.wikipedia...by_average_wage  :)

 

BTW we're getting spamed here if you haven't noticed it: http://community.cas.../statuses/all/  :wacko:

Yeah, the status page is full of spamming links starting from 2016 to 2018. Some of them are even in russian language.

I met a russian spammer just last month. He/She is spamming around the forum about welding, until 2072 came and deleted all his/her posts. We even had a nice talk in IRC. ;)

And... You replyed the post that was made three years ago.
