I can't understand why, but Raghav, a help person, has either closed their account, or has been banned. Does anyone have any idea why?
It was probably the spambot which closed it. Because your friend have been so active in the groups and posting so many news items, the spambot (which can be very trigger happy) automatically closed down your friend's account, thinking that your friend was spamming.
It has happened to me on 3 separate occasions. I have a group of my own and we were having a very large TM so I sent notes to multiple members to get them to join and then my account was auto banned by the spam bot.
Hope this helps
