i joined. First "friend request" i got was from some Bitcoin marketer who had subbed to "every" interest group.... I couldn't see any way to flag this person, report them for spam or otherwise mark them as someone I'm not interested in. I was also spammed by the "new posts in..." for subs i had not joined and have zero interest in getting email from. In short, this feels like something from the good old days when we all thought the internet was a small and friendly town... What the hell were they thinking!
