To be clear, are you personally accusing me of trying to take advantage of the system? That's uncalled-for, and against the site rules too. I'm not offended and I won't report or blacklist you or anything, but I recommend that you edit your comment before you get in trouble.

Regarding private profiles, here is the rule:

Does my Steam profile need to be public to use the site?

You'll need to switch to a public profile when registering, so we can confirm you have a legitimate Steam account that meets our minimum requirements. From that point on, you can use the site with a private profile, however, if you wish to enter giveaways, the site will ask you to switch to a public Steam profile once a week to bring your account up-to-date.
