They usually ban VPNs for website use but allow them for seedboxes (sometimes requiring approval). The rationale is to stop account sharing and ban evasion.
I don't know but it's pretty suspicious to ban VPNs to use something that is illegal in many countries. Hope they don't keep records that can be leaked.
It's really not. Even if they aren't recruiting new members you can buy an account or invites. You could also prepare alternate accounts ahead of time.
