Getting repeatedly banned for no reason

So, basically, on the 19 of january my main account, that was used since 2017, got blocked. The email said that it may be because of “suspicious activity, spamming” and all of that stuff. Obviously, I never done anything of that, so I tried to reach to the support. They answered quite fast and actually unblocked me, saying that I might had been caught in their “spam filter”. As I was celebrating the fact that it didnt took long, as soon as I logged in, I got blocked again. For the same reason. After contacting support once more, I tried to log in again, and actually got to write a few messages, but as I was trying to log into the account on the main client (I was testing it on web-version), I got blocked AGAIN. The story repeated itself one more time, as I decided to write here. Maybe someone had that problem before and has any tips? This account is really important for me as it stores so many memories, but I cant even log in.
