If the files are exact copies, then MD5 checks will catch them; tweaking so many files just to bypass this could prove to be too tedious of a process for people to bother exploiting it.
However, people could create scripts for others to mass-download, -edit, and -upload their files accordingly to reduce this tedium.

we’re talking about reducing “crap data” which is data people don’t care about long-term. If you care enough about the data to copy it manually more power to you. If you don’t care that much, you’ll let it get purged.
