I'm guessing you're getting your scripts from the free for all section or the first scripts section. The free for all section is likely to have out of date scripts and the first scripts section is likely to have highly detectable scripts. I would recommend learning a bit of basic scar and post 10 useful posts, then wait a week and you will get access to better scripts that are much more reliable. Any script that has 'FindMime' in it is very outdated and will probably get you banned if you can get it to compile. Also, make sure you have SRL rev 14 installed if you want to run decent scripts as that is what most new scripts use (some use 13 or 12 and those will still be fairly reliable).
By reading this signature you agree that mixster is superior to you in each and every way except the bad ways but including the really bad ways.
