Interesting. I’ve come across two of those today.
There are actually a couple of people who have a master list.... When they are confronted they leave and use another name....
One name was working 24/7 and using several people to post...You could tell by the posting style. Once the technique is mentioned or the above link is produced they often back off....
Many have started using FR_mail to communicate instead of posting their ideas on public sight....Drives em crazy.
OTOH if you suspect that is what they are doing...let the mods know your suspicions so they can watch the poster....DO NOT play their game. Ignore their posts. Welcome to the world of OBOMBa
