Winner not activating older gifts...

I just had 4 public giveaways... I have used sgtools to look at them. 2 of them came back with "Whitelisted" games (All of these are most probably activated, you just have to check if the user owns the base game for entries that are goty, deluxe, complete, etc...). Neither of them have activated the games in question, I went and checked their profiles.

I was going to ask for a reroll with the evidence I can put forth on them, however when I went to select a reason it specifically say "Regifted or Did Not Activate Previous Wins This Month". These wins occurred in April and March 2016, so not within the month.

Should I still be asking for a re-roll? (To be honest, one of the profiles is pretty good, given away a lot more than he/she has won)
