I really hate it when people post links to these websites, which are all shops.They're probably fake accounts controlled by malware, and theyre really annoying. maybe links should be disabled in comments in AG3?
The links are indeed advertisement bots OR people that made an AG account simply to advertise their products here... the proof of this misconduct is needed for a mod or admin to see it and act upon it and it will usually be deleted when taken care of in the end!
Keep reporting and flagging those comments when you see them people! =)
