Infinite account suspension without any reason

Hello can someone help me with "Your IP has been suspended for due to Suspicious Activity - RB".
I've never done anything and it's suspended for so long time like an year i don't get it.
Can someone please check this thing and remove the suspension?
It's really frustrating because i came back from 1 year break and wanted to donate and i can't what should i do...
I simply can't do anything and i don't know why my IP is suspended.
It is really sad that no one checks the in-game tickets in Blackrock realm.
I will be really happy if someone help me with this, it's from 1-2 years and i don't know why!
Best regards bogidr16!
