So I got set up from JSP once in a public game and now before I kill someone's clone in a private game they invited me to I feel it necessary to clarify it is a transaction for an implied tip (assuring them they do not have to give it). This is so the SA will stick next time. Is it enough that it's a private game they invited me to from JSP? Like is the other part necessary?

what

The question is: If I join a private game from JSP with someone asking to kill Dclone, and they have set up the WP to get a PK, would that alone be considered a "scam" even if I did not negotiate a price or say it was for a tip.

probably not. even if someone were to try to kill you with a bad tp, they'd probably counter that you've got a shit dclone killer that couldn't take two mob hits while loading.

so tele there yourself if you're paranoid

Ya I've done that, but my zon Tps so slow :).
