If someone decided to bid and raise it to 670k, the bid would've been overruled by a Mod according to your original post. Which means the prospective bidder would have lost out due your own misinformation in your auction comments.
Secondly, it is your problem if you cant conduct a proper forum auction. You're liable for what the bidders adhere to in your own written rules. Also, there's zero excuses for not knowing the rules when its explicitly written in detail for you to understand. https://www.pokemonrevolution.net/forum/topic/119691-url
Third, lol, don't come around here and think you can enforce your own made up rules.
Geezzz man, simple things yall cant get right around here.
