As long as PM RP isn't forced (not being able to ignore it), sure why not? But maybe there should be a way to limit it for kidnappings etc. Some way to limit outgoing PMs/CB messages etc. while you're being kidnapped. Perhaps /gag [id] or something like that.
It's weird, every time we take a few steps forward to improving the roleplay quality around the server, we usually take a few steps back afterward...
+1 for gag [id], like I said, this is my only issue with PM/CB, using it to get help when you're cornered when you're not supposed to.
However, a few weeks ago, when I got kidnapped, I didn't PM or say anything to anyone, but the FBI PM'd me saying the knew what was going on and they chose to ask me what the last location of my phone was before they smashed it (I turned it off).
So maybe high ranked FBI Agents can track where players are when their phones are on automatically (?)
