Here’s my take:
The domain aftermarket has a big problem… it exists. This market shouldn’t ever be allowed to exist in the first place. ICANN should’ve blocked this bullshit a long time ago and forced registrars to just let domains expire and free the space. Also add a few provisions about unused domain names and about selling them.
Wait, is it bad that I purchased rights to 5 domains with my name on them but haven’t decided what to do with them yet so they’re just empty?
As long as you keep renewing them you should be fine.
