When it comes to an item like the figurine written on your nickname, it is rather simpler to prove... however, I heard that recently one man bought a GM doll from someone. that someone stolen this doll and sold, but was deleted along with the character buyer (he didn't know about theft)
From what I know, it depends on the material where you have it. Cipsoft helps when you report it breaks down to the police because it is the legal threshold for theft.
Recently, one streamer from my country was robbed, giving the item to the player who was impersonating the company. he didn't give him money. he had it recorded, he has evidence and the amount was large so cipsoft agreed to help him. maybe he'll get his money back.
whereas I having no clues who robbed me, I can't do much. 150kk was stolen from me, some of my fault but similarly in the case of this guy - he also trusted random. I have evidence, but it's not enough to report it to the police. I also don't have good English to fight for it.
It all depends on happiness. I know people who received help after the theft and managed to recover money.
