I did a bit of looking into it, talked to their tech support (they didn't even ask my name, just the website), and this is what I got:

"Alright, I see that the account was suspended because there were a large amount of connections and it was affecting our other customers. Also, it looks like they found some adult content on the account as well. You would need to either limit the connections, delete the files that were causing that many connections, or find a more dedicated host that can handle that many connections. You would also need to remove the adult content."
