... When we use the term "ghost guild" don't we mean a guild that disbands after it's done attacking for the day? So if the guild sticks around, just doesn't hold onto any hexes, I think it needs to be called by some other term.
Yes, you would be right, while they are "acting" ghost guild like I guess they aren't technically ghost guilds. It's a rather annoying guild? Really the behaviour of attacking sectors just to release them is annoying but you'd never be able to stop it and we probably shouldn't try to. I guess most of this fustration is born from large/strong guilds having single people or small groups break off and form fake guilds (ghost guilds) to avoid potential seige losses. So not surprisingly any behaviour remotely close to this cops flak.
To clearly define types of guilds we could say:
Ghost guild:
Temporary existance, small membership (less than 10) and never retains control over sectors taken. Avoids the high siege goods losses that might occur, making retaliation strikes easier, thus exists to break the limitations in place.
Annoying/Demolition guild:
Permanent existance, varied membership (could be any number of people) and doesn't intend to retain control over sectors taken. In it for the PvP points or in it to wipe others off the map, not directly trying to break rules for the advantage of one guild over another.
Legit guild:
Permanent existance, varied membership and retains all/most all control over taken sectors (not counting ones forcefully removed) In order to gain rank and power for guild level.
(there may be more traits but I think these at least are key)
So really the OP contains all that is needed to combat the ghosts while not removing any other type, guild must have existed for "x" time period and guild must contain 10+ members. The only problem is that it would penalise annoying/legit guilds with less than 10 members but personally if you have less than 10 people in your guild you really shouldn't be participating in GvG (just like how people in BA can't participate).
@rusty_nail, while some are ghost guilding for PvP points i'm not sure that splitting towers would do anything to stop it... it might actually encourage it (possible increase in medal reward because you can top 2 towers). Personally I think PvP points should be removed from GvG fights as PvP is surpose to be a neighbourhood thing (as I mentioned in an earlier post). But even if they were removed/adjusted it sort of affects all types of guilds and not just the ghost guilds, it'd also do nothing to solve the initial problem of avoiding seige good losses.
(Because this has come up before I'll mention it again here, if your main guild is facing costs 1000+ and uses ghost guilds to remove opposing defenses then yes they are still paying the 1000+ to later take the sector but if any of their "fake" seiges are defeated they only loose 5-20 of each good and not the 1000's they would have otherwise. Thus ghost guilding IS a cost saving method.)
