This is an on going issue with Spam users registration regardless of our Honeypot plugin implementation.

Hi @dung,

This isn’t quite like what you mention, but gives a lot of good options for identifying spam users via SQL: Collaborative list of spam user patterns - #2 by marc (note that some of the more up-to-date suggestions can be found later in the thread)

Hello @rcgillis , thank you for the link. I will definitely work on the low hanging fruits by using the instruction in the post while waiting for someone who can help us with the construction of the desired query.

Best,

Dung.
