if your any good at php (and tbh if your starting a file host you really should have one on your team.)

You can have a list of flag words, if one of these words is found in the uploaded filename it flags it so you can check it later (eg porn, warez, mission impossible 2 movie blah blah).

Also id recommend any file that you remove from the database for not compling with rules to md5() or sha1() the file. Store every sha1()/md5() in a table within your database, whenever someone uploads a file, sha1()/md5() it and check it against that table. if it matches it means someone has uploaded the same file again and you can safely remove it (md5 and sha1 are pretty **** difficult to match duplicate different files, and if you really dont want to match duplicate files do a md5($file).sha1($file) and store that instead.

Hope that helps
Edit: is there any sites that use xtrafile online?

Tons of sites use XtraUpload; we have given away thousands of free licenses.
You just have to find them...

FasterUpload.com is the largest site so far using XtraFile's script.

Our file hosting site has nearly 300,000 members. We just delete files when we get a DMCA complaint. We get 3500 ish new users a day, with more than 80GB of files uploaded daily, it'd be ridiculous to even try to keep up with so many uploads. We have a clear TOS though stating that all files uploaded are the user's responsibility and that we don't allow any form of illegal uploads.

During peak time we can also have upwards of 2000 people connected to MySQL and 200-300 visitors using the actual site at a time. (registering, uploading, etc..)
