I know this doesn't really help with the idea of catching who tagged the raid mob first but to deal with people just sitting in the zone for far too long with a raid force how about just enabling some anti AFK code that disconnects you after 1 hour of AFK or something like that?

Another thing that could be useful is to move people to the safe point that the succor spell does(I know succor is not classic) if they disconnect via AFK in certain zones. This would prevent people from allowing themselves to disconnect at spawn location of raid mob and then just logging back in.

You could then have a policy where if someone stayed connected and in the same zone for more than 12 hours(you could make this longer) straight you could slap a temp 1 day ban/suspension on the account. If someone stays connected for more than 12 hours straight in the same zone then that person is either using some sort of macro software or they need to have a break from EQ forced upon them.
