I won't blacklist you for saying thanks. I won't blacklist you for not saying thanks, either. (Seriously. I don't care enough or have the time/patience to do that.) Just enter and maybe you'll win? If you do, please be sure to mark it as received. Otherwise I think the site will make it harder for me to give away things in the future and that'd probably be bad.

Good luck. You'll get a Steam key if you win.
