Yeah you're right, but let them break more rules continuously, they have all the right to buy as many chances as they choose and if they continue to be an idiot they will get banned again, simple as that. And I doubt Badspot would change that, he gets money, not only that, but those people get punished for spending money, that's literally their punishment, spending money. Seems like a suitable punishment for forum bans.
And they shouldn't, people can spend their money how they like, it's probably not the best choice, but they do and will.
People only gave a stuff at the time because making alts were free and easy, if you read Badspot's development thread he actually tells you why he made it so you can buy as many chances as you want. "Since the forum now requires you to register your Blockland key to post".
But people who do it just to avoid a week-long ban are morons. There's also people who abide by the rules, but also use them to their advantage to antagonize people.
Then there's people like Jazz, who constantly empty their wallets out over a lego-forum just to antagonize the people on it, rule-abiding or not. These people are the only ones who I can actually see getting their own chances, as they have most means to forget it up and continue to give Badspot money, the other people who ben the rules or just activate another key just so they can avoid a short-ban and continue to post are the ones who should be banned as soon as they activate.
