Dear sir
I appreciate your request to join BABA, but our group was recently trolled with porn, so we decided not to accept people who have been members of smogon less than a week. I did send you an invite to New Group - a group for people new to Smogon where we can get to know you and then if you still want you can become a member of BABA. I hope you understand.
Thanks
