One of them, wasn't a surprize, I knew I was deleted long ago and that person has also left the forums long ago. Too bad really.. That person was cool.
The second one, I rarely talked to anyway.... probably got offended because he/she was blocked.
The thrid, I don't know who the hell that person is, but the email address has "juve" in it so it must be from here. Probably some person who saw my email here and added me, then of course, I blocked them and deleted them.
Anyway, 90% of my contacts are blocked, so it's probably my fault that they haven't seen me online in a while.
