The Bottom Line
In case legalese is not your thing, the bottom line is that if you do anything with your site that is illegal, immoral, unethical, or spammy, a) you’ll be shut down; b) you won’t get your money back and c) I can come after you to recover damages. If your site’s been hacked, I can shut it down until it’s proven clean; if it’s out-of-date, I have the option to update it or shut it down, as outdated web applications are a vector for spreading malware.
In case you want full disclosure, the terms of service and acceptable use policy follow. Have fun.
