I don't think people should be able to be unbanned for racial slurs. When people are banned, it's for a good reason. If there's any problems with the filter (mistypes resulting in ban), those can usually be resolved. I don't think we have issues hitting our donation goal.
I would be weary of buying used off craigslist, it's possible that it came out of a GPU bitcoin miner. I would rather buy new and have piece of mind. Just my 2 cents.
