But I think there is no username with "Donkey Kong". Can you point it out please? If there is such username then I'll surely close this thread. 
BTW, I think scammers can always scam with any username so there is no point that I'll become a scammer if I change my username and I won't become a scammer if I don't change my username. I think you got my point. Let's see what theymos says.
That does not matter at all. An admin should not waste their already very limited time on random requests. If there was a good reason behind it, you might get lucky. Otherwise forget about it.

I think you got my point. Let's see what theymos says.In other words, imagine that a member spends 50BTC on bitcointalk back in 2010 when it started, then buys back the 50BTC at market rate. Why would it be a question of "honor" if the forum decided to lower the fee in 2015? If the VIP didn't care to buy back the 50BTC back in 2010, that's his mistake, not the forum's or its future members', isn't it?
It's not his mistake. It costs 50 BTC, end of story. Theymos has said that he will not be lowering the required amount but might introduce lower tiers IIRC.I think you are wrong again! We always look for value not the numbers. Worth of 50 BTC in 2010 is definitely not same as in 2015. So if admin decrease the donation amount, there will be no harm done. This will never discourage previous members as the price equivalent is same. The value is same. Otherwise you'll have to buy a pizza at 50BTC now if you had bought one in 2019 at that price.
There is harm and I would feel offended if I had donated at the time. If you are comparing the price now, then consider how much potential USD value they have lost with that 50 BTC donation to get a rank that you can now acquire for much lower. Technically there is no right and wrong here since this is a subjective discussion. Ultimately theymos decides and I am strongly against lowering the required amount.
