Same thing happened to me. I had to create a new account. The first thing I did when I created a new account was ask why this had happened to me, someone told me that if a comment of yours was reported, and if they had a valid reason for doing so, then they could suspend or even fully ban ypur account. Of course, that didn't happen to me. I just couldn't like or post anything.
If it's helpful ur welcome and if still doesn't work so tell here on mangago official complaint area -
