Admin in Sythe Steam Group sending Phishing Links

Some guy from the Sythe Steam group randomly added me to a conversation and then proceeded to link me his phishing link.

I understand that there's nothing you can directly do through Sythe, for example, banning his sythe account, so this should probably be meant strictly for the actual admins of the steam group.

EDIT - Before someone starts stating that I'm calling out an admin, the guys name is "Admin"

 

Noted.
