I think it is possible, maybe even probable that a non scrupulous script installer would have used a copyrighted review as an "example" of what the script can do and to demonstrate it's functions, however, that being said,

I think it would be prudent on the part of the offending site to, once the copyright infringement has been pointed out, to immediately remove the offending material (looks like that has been done) and offer an apology if the error was accidental as suggested in this instance.

I think the offending site needs to take the more gracious approach upon realizing the error, and certainly should not try to be vindictive or defensive, understanding that copyrights are serious business.

I think the offending site should realize that gaydemon has a legitimate right to be very upset and should offer remedies for the infractions instead of excuses or veiled slander.

A gracious and humble apology coupled with a reasonable, no fault, explanation and possible assistance in tracking down the actual offender (script installer) would certainly go a long way toward healing the damage done in this situation.....

Certainly responding with taunts and cheap verbal attacks are not the proper way to make this better for all involved.
