Hi,
first a thanks for the nice giveaway :o)
Please don't take my following words in any way against you. That are not the intention.

I want to please you that you make no "free for all" GA's under lvl 2+
It's nothing against the real, nice, friendly players on lvl 0 and 1 but on 0 + 1 are 90% autojoiners, bots and extreme leechers (3 years+ on sg, never given anything out or only 1 GA to be on lvl 1 -to access more with a higher rate- but taken hundreds of GA's).
So i think you feed the wrong people with open for all Giveaway(s) under lvl2 without any security measures.

It give many security measures you can use too. By a part you can avoid the lvl2+ and support all the new/low users without supporting the bots/autojoiners/leechers.
Examples: Forum thread, jigsaw puzzles, puzzles, itstoohard, sgtools, hidden text or links, edited links and so on....

When you want give it out to lvl 0 is it possible without problems.
Only use "invitation only" and Create a Forum Thread.
With this way a lot of the bots, autojoiners and other not so nice people found not the way into your GA's (easiest security measure so not perfect but better then nothing ;o)).
By this way i have no statistic numbers because i saved my thread with sgtools too :o)
When you use sgtools (sgtools.info) you can set rules. Partly set a hook, partly fill in 0.5 or anything like that and when you are experienced you can set custom rules where as example all that own CS:GO can't join your GA or only a fixed number can join your GA or only people with a wishlist smaller as 400 ... or whatever else... the possibilities are very high.
I can say the winners are then real players, no 7 days waiting on a hook, they found the word thanks and the work after the end of the GA is near zero.
I give my stuff mostly out to lvl 1, then i can set a real cv ratio rule too (in my case 0.5 = maximum won double of the given) :o)

Here you can see how you can use Questions.
From "Are you a bot" Questions that can all users solve to Questions that nearly nobody can solve ... you set the difficulty complete by yourself.

Hidden text/links, as example when you link a picture and the picture description shows the 5 digits of a GA (in your GA right now K2CzS)

jigsaw puzzle = http://jigidi.com/

Hope that helps. When you have questions i try to answer them.

Would be great if you think over that and look if any of that stuff fits for you too.

Thanks, happy winning and gifting and have a nice week :o)

friendly regards
