I didn't pay close attention but if ReplyGuy only does one-off posts, what then?

My approach as advertised since over a year now would be to give new pubkeys very limited allowance. No links, no images, little tags, no mentions and only few bytes. 

 One offs won’t make it out of our intermediary database. 

The idea is to collect and evaluate multiple events (without losing them) before approving a new pubkey and distributing those events to the relay.
