Okay, Im not sure what to do now

So basically I got supraball with the gleam.io giveaway and like 20 minutes after I won the same game on steamgift as well XD So naturally I contacted the giveaway maker, requesting a reroll as per the rules, to which he told me to just mark it as received and give away the key to a friend of mine.

before you ask: I didnt had the time to remove manually my entries to that giveaway because it already ended at that point

I cant help but ask if its exactly "within the rules" ? not trying to name and shame anyone obviously, wanted to make sure.
