I think that this system wouldn't quite work as the server stands right now most of the players that seem to get kidnapped atm are usually lower enlisted who just wanted to explore the map and happened to stumble upon some Officers from an opposite faction, and even if it is a higher ranked player on the server that gets kidnapped i dont personally think having to change your ign is fair or appeals to alot of players, for some people (myself included) the names we go by in game are the names synonymous with our identities on the server. For instance anyone and everyone on the server who knows me knows i play under the name Broku, when people hear this name they know exactly who i am, if i was forced to change it people who werent on at the time or are out of the loop might think i just up and left the server. Another problem this might pose is for some SOC factions, Currently im playing for GRU and we have a system where we have to let one of the people in command of the faction know when we want our names changed (i assume its different for all factions but the premise is the same)and that would mean if for example i was kidnapped and a PK was called on me i would have to contact one of my leaders and tell them about the name change without confirming it with them beforehand since it would be forced. I feel like an alternative form of RP punishment would be better suited for the server as it is now like becoming a prisoner of war or something which could lead into other RP scenarios such as prison rescue where a small team would sneak into the opponents base and either sneak out the kidnapped person or break them out in a raid like assault situation. With all that said on this maybe a revision could change how i feel on this but for now its a -1 from me.
