Going through your post history, the ATM post was the first you shared content from an external source so not citing it was probably a mistake and ignoring all the bounty posts, the rest aren't really spam, but with all the spamming/plagiarism getting reported, unintentional mistakes isn't an excuse for not having read the rules.

Maybe the mods/admin will take your appeal into consideration and let you go this time with a temp ban, unlikely.
