I was researching a streaming tv script for sale on this forum and I came across this website: http://phpvideoscript.org/ (I still can't leave links in my posts yet, too new) I thought this type of script was legal. Makes me change my mind about making this kind of site....
If you don't host and stream illegal movies and television shows it's legal. The script itself is legal, but apparantly many sites use it for illegal movies.
