Thank you for this PSA. I will not buy from these users because I find this extremely fishy (and multiple times I have thought about buying characters from Almond's resells) - but this has helped me in the long run. I hope this can be settled, and I agree with you in this matter.
A gift is a gift. I can understand if Almond took back a character they bought with their own money (it was their money directly, which was used to gift you a design - therefore none of your direct money came into play with the character. Unless you drew / bought extra art of the character of course and they are using it, which is illegal since you are that copyright holder)
However, taking a character away from you that you bought with money gifted to you is illegal. If someone gave me 5$ off the street, and I used that to buy myself food - if that person came to me trying to take that food, saying it belonged to them, that would be illegal. They gave up ownership and possession of that money as soon as it was sent to you via paypal, and in court, this would legally be in your favor and your ex would have to relinguish the rights of that character to you, since you are the legal copyright holder as records show - the money came from YOUR paypal. Not theirs.
It's extremely ignorant and bad business for HoneyKing to relinguish your rights of ownership to their friends, especially since they didn't make ANY attempt to contact you directly about the issue and try to resolve it. They just went "lol ok" and did it. That's ridiculous and I will not be buying from that seller. Shame on them for doing such a thing, and shame on these individuals involved that are illegally taking material that you hold copyright over as a means to get under your skin.
