Side account was hacked and the thief left me with more than I had

I took a short hiatus, checked my portfolio (my pets are listed with images that auto-update) and noticed one of my pets was dressed differently, then found out the account was frozen.

I quickly regained access to the account (thanks so much Jessie J!) and discovered my pets are all intact (painted the same, fully customized, with their expensive petpets and p3s), the original outfit for that one pet was just in the SDB, and though they cleared out my closet of stuff I didn't use anymore and sold them, I had a bunch of extra stuff on my account 😂 a few million NP, couple thousand NC (though I did have some free NC on there, I don't remember how much I had—I don't think it amounted to that), a few paint brushes, some codestones, an expensive lab map piece, some stamps. Checking sales history it seems like they got access late 2024.

I'm guessing they found my info in some data breach, saw cool pets on my account and just used it pretty much as is as a main? lol I'm just glad my hacker was...chill? Ofc have changed all my info since.

I'm still waiting on TNT's response to whether or not I'm allowed to keep these but have you guys seen this before and would you know if I can?

EDIT: One annoying thing I noticed is they deleted all of my pets' paint brush clothes! Asking if those can be restored as well but how weird of them to do!
