Lauda admits Xanis is his alt (although clearly trying to dance around the subject) but denies that anything Xanis did can be associated with him. Haha!
I agree that given the evidence, it shows a linkage between Lauda and Xanis. One can assume that at some point, Lauda had control of the Xanis account before it was nuked due to the address linkage.
We can assume that the bids on the Xanis account were for the sake of buying accounts... or we can take the other perspective and imagine it being a shitpost.
Given that I had been relatively active during the height of the account sale/shitpost days, I absolutely KNOW that people used to post bids and useless questions on account sale threads. This was to boost their post count so they could farm their peanuts. The very same thing happened in the Lending section and probably still happens now. "collateral?" "read the sticky u need collateral" "lol u won't get a loan without collateral" "haha these newbies" etc.
The chance of Xanis doing this is non-zero. You could say it is more likely that Xanis was actually bidding, but it's uncertain. I admit that I had also occasionally posted on the auction threads about asking for more information about the account sale (just for the sake of posting).
Note how I agree with you but have my own opinion on the matter.
