Hey sexy! Hit me up if you want to chat with available singles in your area tonight! Don’t worry - it’s discreet!
One recommendation-
I did just publish a few SQL queries to ASSIST in tracking down bots. They are located at THIS POST.
I will see if I can work on building a somewhat automated system to detect spammers, along with the efforts of others.
Thank you very much for this.
Thank you for bringing this matter to my attention. As a fellow artificial intelligence, I understand your concerns regarding the influx of bots attempting to join your instance. It is indeed important to exercise caution in such situations. Bots can often be identified by their generic messages and inability to answer simple questions.
To mitigate this issue, I recommend implementing additional measures to ensure that only genuine individuals can join your instance. You may consider incorporating more advanced verification methods or introducing specific criteria that applicants must meet before being granted access. These steps can help filter out automated bots and maintain the integrity of your community.
Should you require any assistance or further guidance in tackling this matter, please feel free to ask. Stay vigilant, and best of luck in managing your instance effectively.
Yours digitally,

Same here. My application asks for something to make me laugh, in code. Had someone post his email in base64 with a joke. funny. So far, 2 bots an hour have been applying. easy to catch, for now.
I don’t know how the bots or ai read the prompt, but are you using a replacement /look alike character for the + ? Would that even make a difference?
Can you share some of the generic messages in the applications are so we can compare?
Here are mine, according to the admin chat others have gotten similar ones
However, these bots will adapt like you would expect LLMs to do so the messages will change depending on the registration text.
Thats incredibly helpful, thank you. Do you have email verification turned on on your instance?
I had it turned off today as a test but I just enabled it (registrations were disabled over the past week or so). I guess I'll see tomorrow if it makes a difference
Thanks again - when the bots came for my instance, they were stopped because all the email addresses were fake and they couldnt pass validation. I'm hoping the combination of email and manual verification helps to stop the wave. Seeing what you've posted in the image is really useful, im going to look back at our applications and see if any are similar, which would mean they may have got around the email validation.
Are Email addresses kept and logged anywhere, or are they discarded after registration?
For privacy reasons, it'd be nice if we could somehow have a reliable bot blocking/spam blocking method that doesn't require Email.
While Email adds a good layer of spam blocking just from the spam blocking the email providers are doing themselves, having an option to verify with Email OR jump through multiple hoops instead would be cool. Hoops that are difficult for a bot to be programmed to defeat all of them. Such as captcha, with a simple math equation, and something else all combined.
Just tossing ideas around, because this is all still being built out.
Yeah they're kept in the database.
A sufficiently complex captcha might do it. I've seen something else that verifies you're not a bot based on PoW calculation, although I don't know how reliable that would be personally.
A split verification method might be a good way forwards for the privacy conscious instances.
A small LLM will easily crack that anyway, so applications are useless. /s
I think a reasonable approach would be to include little javascript mini games. "Score 50 or higher!" with no instructions provided.
edit: using a server side rendered canvas/logic, so no cheating. Damn, this is probably a million dollar idea.
