I guess its rumored that all these sites are now out of buisness or on hiatus. Lots of developers reporting not being paid out.
Brace yourselves for revokes
OtakuBundle AKA GoGoBundle (yes they're the same business) apparently went bankrupt either at the end of 2018 or at the start of 2019 and the Orly Gifts website says that they're "taking a break". I found a forum post on Steam where a developer said that they haven't been paid out on Otakubundle and revoked all non-redeemed keys.
