The script would be fairly easy to make for any person already familiar with scripting. If you don't know Java or how to script then no, it wouldn't be easy.

The reason those scripts are not allowed has little to nothing to do with scripts crashing prices. I was speaking with Alek the other day and historically scripters who have released those scripts have made quick sales, left the scripts to rot, then left OSBot with a bunch of refunds to deal with.
Do I feel these scripts should not be allowed (as premium) because of this? Absolutely not, they should just be vetted for quality like every other script, fear of abandonment is a lame excuse in my personal opinion, but I don't make the rules and people around here rarely change their minds.
