This appears to be unsolicited advertising (i.e. "spam"), and while advertising is allowed within your own giveaway description, you have chosen to post this in someone else's comment section. Not cool.

You have been on the site long enough to know how we do things, here. Instead of suspending you, however, I am going to give you a warning. Do not post such links outside of your own giveaway descriptions, and do not spam.
