OPEN How do I know if a plugin has a crap or not?

[TheOneAndLonely]

Hey everyone, I am considering buying a rank to download premium plugins, but I have an issue trusting that files don't contain viruses. Are all premium plugins cracked by staff members? And if so, how do I know which plugins are premium or not?

Thanks
