What did I do? Banned from Bitcoin? At least it's temporary.

I'm a noob in crypto and asked what I thought was a legit question because I needed to learn. I am now temporarily banned.

I honestly really thought bitcoin had slow transactions. So I was asking how Steak and Shake could really process payment fast enough. I didn't know about bitcoin lightning. So I made the mistake of mentioning coins like ADA or SOL and XRP since they claim to have speed. It seems like decentralized and POW = slow and POS or centralized = fast. So I honestly wanted to learn how this stuff works and have someone correct me as part of that process.

They replied to me like 4 times, one of them basically took my self-deprecating comment and threw it back at me. ( When I posted, I was just trying to let everyone know that I realized that to the subreddit, it might sound like a dumb question.) In one message, they said I could reply back to the moderator, but in another of their other messages they said I was muted and *couldn't* reply to the moderator.

I still don't fully understand why lightning is all that and a bag of chips. Maybe it is though. Originally, I wasn't sure if bitcoin lightning was a coin or a network. Now I know that it's a network and bitcoin is the token used on that network? I still need to figure out what there's these other coins that are making security and speed claims. Why do any of these other coins exist? What in the world is BCH?
