Personally I have never seen a player take over a Chardok camp on blue from someone who trained out, /q'ed, or gated and then immediately came back. Players on P99 tend to be respectful of players who are camping something.
If you have played in the revamped Chardok, you will have seen these tactics employed on many named mob camps in this zone. I myself have gated out or /q'ed faction hits plenty of times. You can see an example of this here:

It doesn't really matter how you interpret the P99 camp rules in this situation. Unless you are the type of player who enjoys lawyerquesting camps away from other players, you do not typically see this behavior in Chardok.
If people in this thread want to become Chardok activists and start taking camps from people who trained out, /q'ed, or gated to prove you can do it via the PnP, go ham I guess. You won't be making friends this way, regardless of the outcome.
