Thank you so much for your clarification.

Indeed, the username sydesjokes looked familiar to me. (But the other usernames such as vapenation/fiftysats/superheroes appeared alien to my eyes.)

Now that I know sydesjokes is to be avoided, could you get me out of the blacklist? I myself am a "rule of law"-based person, and I'll deeply appreciate your helping me.

You're the best! Cheers! Peace and blessing!
