Is there any rule on SG that your region-limited gifts can't be more than 50% ?

There is no rule like that, it's just that the person who blacklisted him was personally against it.

One thing are site rules, another thing are the rules that each person of this community can use. If someone is blacklisted by a user, he can still enter in another giveaway from any of the hundreds of people creating giveaways daily. Please avoid drama.

There's ROW-users that create regionlocked (e.g. cheap russian copies) to boost their CV.
Then there's non-ROW-users that pay a lot more than they should just to give everyone a chance to win a game.

As you can see, some people abuse the system, others try to find ways to provide nice gifts. Of course most of the non-ROW-users are not able to create such giveaways as they don't want to use grey markets but if someone wants to blacklist them for that reason, it's their own decision.

PS: Blame Valve.

So not to create drama, but... there's no SG rule; just as perrolijo mentioned each user can blacklist (and whitelist, mind you) for ANY reason he/she/it believes without further authorization. It's personal. Now, it could be taken as discrimination or racism, kinda. Why? well, it's not our fault that the system decided to implement region restrictions and we happen to live outside considered ROW.
Furthermore, not only the simple fact of giving is ignored but also punished (being BL'ed) because we cannot or would not provide ROW games.

Now, as I said, no drama, but SG is composed by users, there is "cg" giveaways, of course, and devs too, but that's just a drop in the sea.. compared to the amount of users. If they, each and everyone decided they just want ROW giveaways then we're pretty much done.

I've been here around 3 years. I've been in other sites that implemented region restrictions in their sites so it's a NO-GO for us. It's their business and so far nothing can be done other than just abandon such site and look for greener pastures..

Even humblebundle implemented region restrictions tho conditions are unclear at least to me, so, most affordable gifts (bundles) might most likely be regionrestricted ones; those in our (same) region would be happy as it's less competition; but the creators are the ones on the sharp end of the sword, figuratively speaking :P

Anyhow, hope it doesn't become a thing, but we have to respect others people decisions that are not part of FAQ and common rules and social behavior in this kind of communities.

Have a great weekend :)

There is no rule about it but as Archie has pointed out regional restricted GAs are like Blacklisting without the Blacklist.
Image a user created exclusivly region restricted GAs: All users from every other region can't enter any of their GAs just the same as if they were blacklisted by the creator.
If that person only won region restricted GAs from his own region there wouldn't be any problem but normally they also win lots of ROW gifts while only giving back to their own region.
I personly haven't blacklisted anybody for that reason yet but I understand why many people consider it a problem.

It isn't a rule that's set in stone, as i personally see giving away only region-locked games not as bad as giving away only in small, exclusively private groups, since with region-locks it might not be their choise that they can't get ROW copies.

It just seems unfair to them that they can't win from you, but you can from them, which kind of works as if you would have blacklisted them.

some people think it's unfair that users making onnly region-locked giveaways can enter theirs. it's 50/50 for me, since they are as right as someone complaining about people making mostly group giveaways and entering public ones.

Please, no! Not this argument again!
There's no need to make a site-wide rule to discriminate against people already crippled by the system.
If you really want to, just use SGtools to make custom rules, or some selective blacklisting.

I don't blame region-locked users for this, I blame Valve.
Besides, like Mullins said, giving away only to groups and entering public giveaways is just as bad and no one seems to care about that, so why should I care about region locked users entering public giveaways?

And here I thought the rule was that they couldn't be more than 50% maroon....
