Got it, is there any other limit relays apply?
For instance: what if i make 1 request specifying 30k pubkeys expecting events from las 4 days? Does the relay respond to that? Or they may drop the connection?
Discussion
Some relays (like ours) impose tag limits too. Ours is 2000 tags. The total event size (in bytes) is also limited to around 100k.
Some have way higher limits and some have way lower. No consensus on what good defaults are atm.
