Third party giveaways that require or reward users for performing profitable actions. For example, linking to a giveaway on another service that requires or incentivizes users to click a referral link, like a Facebook page, follow a Twitter account, join a Steam group, complete a survey, sign-up for a newsletter, or make a donation.

upd. in the closed thread mod literally gave you the same reason. was that not enough?

Post something thats not allowed and mods closed it.
Creates another post to reference the old thread, good job.

So if the author game create giveaway on his side then you can't place it?
This is an example of pure stupidity , bye :D

Seeing as how your question was directly answered by the Supermod (and the people in this thread),
and seeing as how your old thread was closed to dissuade people from using the links you included,
and seeing as how you have circumvented the closure of that thread by linking to it in this thread,
this thread is begging to be closed, also. Therefore, I will go ahead and close this thread.

As you have already been warned about this, previously, I was thinking of suspending you for purposely violating the rules, however you are already under suspension. Since I am feeling uncharacteristically generous, I will not add to your time off.
