I check all my deleted post. I’m sure that it's not a spam because it's same quality on all of my post. I notice that this an attack because all the reported post was made a month ago and its in consecutive order.
I doubt it was a personal attack, even if someone reported yourself out of malice, it is up to the moderators to decide how to handle the case. I have reports that are left handled for months, probably because the moderators consider the posts to be in a gray zone. For your case, it could be that it wasn’t that your posts were spam but the threads you made the posts were deleted by the OP or moderators. Still that would not have resulted in a temp ban, I think you got temp ban for something else. It would be much easier if you provided samples of some of the deleted posts.
