Both of them were interested about what theymos thinks about Lauda. I could think of one person interested enough about what theymos thinks about Lauda a.k.a QS. I could think of one person who'd be willing to spend a lot of money to hurt the ~Cat.
Strong logic on linking me as a bought account by QuickSeller. /s 
Shared interests happen all the time on this forum. If you really think there is only one person interested enough about what theymos thinks about Lauda, you're misinformed.
I believe the ~Cat has enemies who'd be willing to buy DT1-2 accounts to use them against her.
You are forgetting that those enemies would have to find a DT1/2 member willing to sell their account. In addition, any feedback or exclusions done to other DT members is going to be heavily reviewed and potentially countered, which has already happened a few times, so if enemies are trying to buy DT accounts for the sole purpose to hurt Lauda, it's not the best use of resources and will likely backfire.
