I don't think its bad, free premium scripts for a 10 year old modification for a 14 year old game. At LEAST I don't feel bad about buying them afterwards when I get them for free.

My friend thinks it's bad cause the script developer put work into making it but I don't agree. Yes they put work into it but if they really didn't want it to get leaked there are ways to prevent that. Plus if you run into any issues on a leaked script you have to figure it out yourself. Most content owners don't provide support unless you buy it.
