Same. It was extremely frustrating because I had written a long response with several references to support my argument and I was just unable to post it, getting a generic "Something went wrong" error message. I thought it was a temporary error and saved the comment but after trying several hours later getting the same thing I realized they had actually blocked me.

Maybe it’s worth creating a throwaway account and posting the message that way to make sure your point has been made.

I've honestly considering it but I'm afraid they will just say "lol you created a new account just to say that? pathetic" or something.

I think if you address the coward blockage from the get go you’ll keep the upper hand.
