Humble store always cancels my orders

I asked them and they told me that my account was blocked for future purchases, but they did not tell me the reasons

They put a cooldown on the multiple bundle buying. I usually have to wait a few days, up to a week, before I can buy the same bundle again.

I haven't created gift links for more than 2 years. Never buy more than one copy. I have few gift links created in 2018 or before.

+1 on this. Got Shadowbanned as well even tho I never buy multiple Bundle, nor create a giftlink (most of the key is for my own library).
I ask the CS more than once and their answer is as generic bots sound as usual to the point is super annoying without explanation nor the reason.

Well, it became the very best solution to not spend any penny on bundle as well as on HB. By Shadowbanned by them, all is left is a monthly choice which is I've just canceled my subs due to very weak bundle.

I can no longer buy anything?

.... isn't that theft? Taking your money and giving you no goods/services in return? And how do they know you're an active giveaway creator? Do you have your Steam profile linked to Humble or did they really go into all the trouble of searching for you?

Humble is a really weird website, they kinda claim that they're banning people who create giveaways to help/protect developers, but other websites don't seem to have any such "obligations". Fanatical doesn't seem to care. Indiegala has its own giveaways and trading sections. All these stores sell games from pretty much the same developers/publishers. Only Humble seems to have a problem with people. Indiegala even wants people to buy multiple bundles through the Happy Hour thing. I just don't get it.
