I have a few bones to pick with this:
The accounts could only be recovered once before the person is banned. This is why a requirement above (such as 100 post count) could be beneficial. Additionally, the person would not only have to put in the effort into adding 7 days to the accounts, but also recovering each one. All to get banned shortly afterwards. To maybe make a few mil per account. It doesn't make sense given the time invested. It'd make more sense to SQ on an account or service.
I don't see the market crashing to 250k/acc. The automated solution is much too complicated and expensive at that price point, and the manual method is much too tedious.
If someone fears a recovery, then they shouldn't use a non-reputable source. The rules of common sense don't change for a different account type. Furthermore, the membership of these accounts would run out before a recovery could be done in most cases, and I assume the majority of the accounts would be used to suicide bot anyways.
