Even though we warn users that everything here is "at your own risk", I feel uneasy about leaving posts like this.
It certainly could be legitimate, but there is absolutely no way that I would trust my system to run some unknown, system-patching software from some unknown web site.
Any ideas how to evaluate the situation? The web site it links to looks ok, but it still seems suspicious to me--it looks too nice

Should we remove the post? It doesn't look to be spam, as such.
Add a warning message?
