Here is what I think: If the things you have said on a social media platform are so bad that you have been banned permanently on some and indefinitely on others, perhaps you should sit down with yourself and ask these three questions:
Was I wrong?
Did the things I say cause harm?
Would I say them again in the same manner?
Pondering your answers might be helpful. Especially if you have more to say and want the privilege of speaking to the same people again.
