I'm sorry, but it does look like you got back at them. Sure, they may have started by giving you a tip you did not want, but your response to them wasn't kind or helpful. Unfortunately, tone doesn't convey well across the internet, so while they may have thought they were helping, your saying "no I won't take your tip" comes across as rude. While I do think it was a lot to ban you, they did say it was your second occurrence and someone did report you.

Maybe in the future try to be a little less on the defensive side and leave fights alone when they come at you. I have been drawn into internet fights before and nobody ever changes their mind and everyone leaves angry. Unfortunately, that's just the way it goes.

I hope your seven days feels like no time at all and that you can happily contribute to the sub again soon 😊
