Busted Paid mods

Why is everyone in the forums allowed to sell their Busted, Introductory level coding scripts for profit? Intellectual theft is apparently rampant in this community, just by comparing 1 script to another you can tell people are just stealing Chunks and placing them in a new file system in a sequence. I’ve even seen a post already where a guy admitted to purchasing a script from someone and was re-selling it!
I’m confused on how this is happening without DMCA’s being issued. Is this just a typical fad that is being allowed to happen?
