Q:

Was this chat ban justified?

@snailboat has been biased on my chat ban with our previous conversation.
The chat that snailboat is referring to here:
https://chat.stackexchange.com/transcript/message/43883427#43883427
Is a chat about a flagged post (which I flagged) of Robbie's, from English Language & Usage as here: https://english.stackexchange.com/review/low-quality-posts/283804 which eventually got removed.
It says this on the said chat too:
*Imported from a comment discussion on english.stackexchange.com/questions/437536...

A:

Yes, it was justified. If I had been online and seen that flag raised, I would have done the same thing. How the comments got brought to a moderator's attention is irrelevant. Once a moderator is involved the entire situation gets reviewed and the steps needed to stop the disruption to the community are taken.
Your behavior in chat earlier that evening also ended up being brought to the attention of the moderation team, and J.R. did try to give you some guidance. If you want to avoid similar situations in the future:

Don't call people names, belittle them or disparage them personally.
Don't ping people over and over trying to continue a discussion when they have indicated they don't want to continue that discussion.
Remember that the community here are all volunteers. No-one is obligated to answer your questions, explain things to you until you understand them or engage with you until they understand your position. 

When you reach a point in the discussion where you start to repeat yourself, stop posting. The discussion is no longer constructive, so just let it go and spend your time and energy on something more productive.

The quality of the post that sparked the discussion is irrelevant.  No matter how right or wrong you are, rule #1 on Stack Exchange is Be Nice:

Rudeness and belittling language are not okay. Your tone should match the way you'd talk in person with someone you respect and whom you want to respect you. If you don't have time to say something politely, just leave it for someone who does.

Your messages said "you're like a child" and you also called someone "pathetic".  This behavior is not acceptable on Stack Exchange.  Please do not pick fights with other users.
When I put the temporary suspension into effect, I sent messages to the other ELL mods as well as the EL&U mods, so if they believe my decision was biased they can reverse it.
