We have been infiltrated by Bots

At least one user appears to be a bot…

The IP address seem to be in Armenia.

The email address is randomly created gmail address so is meaningless.

I’ve now banned this user by username, email address and also via IP address.

I’ve not deleted the posts yet, just so that people can get chance to read them, (not that anything interesting was written by the AI)

If anyone suspects any posts to by a Bot, please let me know

bots are fairly easy to spot: just look at those “posters” without follow-ups.

i’m wondering what the goal of those bots is.

Maybe tests. Maybe there is a Neural Network that is trained using forums.

I hate to say it but wonder if you need to turn on Captcha verification for posting?

Already tried the standard Captcha and it no longer stops the majority of bots.

I doubt any form of captcha would prevent this, because they are already running an AI system, and someone may be manually doing the registration.

Lovely. Dang AI.

most bots are run by the site owners, with the goal to increase traffic.

There seem to be some other members who are only posting responses and not any questions, which seems odd.

I think we will need to start asking people to post to the introductions page before they are allowed to post elsewhere

I’ve doing some investigations and the forum has over 800 registered users who have never posted.

This seems a very high number, as the forum is totally open to browse and there is no need to register.

I don’t know if this is an abnormally high value.

I know that we have around 200 active members who have logged in over the last 1 or 2 months, but I have not cross referenced how many of these 200 are from that pool of 800+

In case these are spam bot accounts I may need to suspend them and force revalidation.
