Some hacks are so simple that the hack releaser may state explicitly that he or she will not be supporting it. If you don't like it, then the advice would be to not install the hack at all. Also, most hack releasers here have day jobs, and have busy lives, and cannot afford to come daily to this site to support their hacks. Especially when most of the time, it's the installer who has made a silly error by forgetting a } to cause a parse error or something like that.
Hack reviews would be great. I also agree that all hacks should probably be released as beta first, and be moved to full release by a mod once it is obvious that it works.
