Considering making some giveaways for the first time in years, need a little refresher

Using Humble Bundle gift links too often would lead to them labelling you as a "trader" and they refused to help if anything goes wrong with the keys because it goes against their ToS.

Basically some bs to not provide support, probably caused by too many people abusing the system. Or just a lazy way to not have to deal with people.

Humble can track gift links so if they see you are sending them all round the world, they may suspect you to be a trader and ban/block you. Best to extract the key and make the giveaway in my opinion. It's what i do. I never use gift links now.

Not part of the SG rules (you're free to do so it you like), but it's generally considered safer for you to use keys rather than giftlinks to avoid any potential issues on your HB account.

Also if they country in your profile is correct. There shouldn't be any restrictions.

With some areas of world keys themselves might end up having restricted versions.

These few quick answers are already enough for me to go with keys in any case. Thanks everyone!
