Sounds almost as far fetched as getting a GoDaddy auction account banned for absolutely no reason.
I think
@Flippa said that the seller wanted a reserve and they notified them at a point in time when it was allowed to add a reserve.
"The request to change the reserve price *was submitted*" "With time to spare"
Perhaps they should comment on when updates are allowed (before first bid? before reserve is met?) and then you can comment on the Platform.
This seems like a pricing mistake and these happen in many cases and the idea that you have to honor it is flawed. I still stand by the idea that when you buy something for a steal... in many ways it is. It makes me unpopular in this forum. I'm supposed to believe the honor amongst thieves thing, I guess.
If he requested a reserve to be added when he could and Flippa didn't act. Then it's a clear pricing mistake and there is supportive evidence of that. Enforcing a mistake is different to enforcing something based on seller remorse.
