I had a builder fuck me over in June 2020 when during Covid, he dissolved his company. He took a 6k advance to do the bathroom (his work was fine by the way - didn't doubt his workmanship) and as he was reputable, we didn't think anything of it as he'd pretty much renovated the rest of the house.
He didn't even tell his builders who were onsite when we found out. We ended up taking on his builders to complete the job as they were great. I just think he took on way too much work (as most builders do) and ended up taking money to pay towards a previous job.
After checking Companies House, it looked liked he'd planned it from early Jan by removing his father and wife as directors and changing his address from his personal address (near where I live) to a holding company where multiple businesses were based.
I don't get why people do this - ruining their reputation just for that last hit of money before folding/disappearing.
For gaming related shenanigans, I think this happened with some French dudes in the Neo Geo scene who were converting MVS carts and selling them as original AES quite a number of years ago. I think it blew up and years of good reputation ruined when they were caught red handed.
