My tumblr account got terminated?

[Kogasa]

My tumblr account was terminated today, and for spamming a tag. I made like maybe 10 posts (at max) on a tag I didn't even think anyone checked. Either way, why on earth would my account be terminated for something so stupid? Is there any way I can get it back? That account was 3 years old. I've emailed support explaining that and that I had no idea the consequences were so large, and I wouldn't do it again. But is that enough? Is my account and everything on it gone forever because I made some posts in a tag? Please help.
My side urls are all still there and I can't reclaim the main url, either. Does this mean I have a chance of getting it back?
