2 brand new accounts and one newbie account with just two post and activities.

Even if they are tagged for because of the reason you started it will still of no use since the person or people (if they are not alts) can simple go ahead and create more accounts and wouldn’t even bother about them since he/they will have nothing to lose.

My advise to you is; before you approve any of their requests make sure to check if they have applied before and deleted it through  ninjastic.space that way you’d be able to avoid stressing yourself over brand new accounts that won’t do you any good.
