You will find that very often questions have been discussed on these boards in the past. You will do the long time users a favor by searching the board to see if there was a thread in the past covering a subject.

There was a fairly comprehensive discussion on this very subject relatively recently. You should be able to reach it via the link I've provided. It also likely would have shown up by searching for keywords such as"screening" "verification" or "RS2k".

Looking for previous threads saves wear and tear for everyone.

is it best to go through something like rs2k or through an agencies website
for screening purposes? Which way is considered safer for being discreet?

Agency screening only works for the agency while screening services usually are much more widely used.  Plus, agencies sometimes get busted and that could expose your personal info.
