The BC.Game-Support here in the forum already contacted you in the mentioned thread.
I am sure that the support team will be able to give you an answer relatively quickly as to why this block has occurred and what you can do about it. I'm afraid that's all we users here in the forum can do

Normally account suspensions don't just happen. If I were you, I would describe the facts as honestly and simply as possible as to why the suspicion of "suicidal threats" may have arisen. This will certainly give you the best chance of having your account unblocked.
