Warpgates can be linked by non faction members regardless if its factioned or not, I.E
When player 1 factions his warpgate player 2 who is not inside of player 1 faction can unlink or link said factioned warpgate without blowing off the faction module
Steps to reproduce for testers
1. Make a warpgate
2. Get player one to faction said warpgate
3. After its factioned get player 2 to rightclick to mark another warpgate (this one is unfactioned can be factioned but I did not for my test)
4. Get player 2 to leftclick the warp computer on the factioned warpgate and enter the cords
You will now be able to use it regardless of the fact it was linked by someone who was not inside the faction.
This leads to warpgates on large servers that admins put down to be unlinked and linked to a homebase of a player
or a warpgate of a faction to another factions homebase etc
