Seems like your "friend" is alt of previously banned account, discovered by @lovesmyfamilies in this post.
https://bitcointalk.org/index.php?topic=2613277.msg53593456#msg53593456So naturally, that account got banned too, as it is violation of bitcointalk rules
25. Ban evasion (using or creating accounts while one of your accounts is banned) is not allowed.[e]
Also, since you are brand new account, I think that it's you who got banned, pretending to be "concerned friend".
