I have noticed that alot of the 500k+ prestige guys have been dropping their prestige to below 200k. I think this is outrageous. Trying to lure people into a false sense of security to gain a quick kill is wrong and the Derv's should put a stop to this method of gameplay.
You can identify these people easily using thse methods
Prinzessin rank under 300k prestige - possible prestige drop'er
8-10 lvl10 cities
Unscoutable for 300k+ people sending waves of 100k scouts
under 300k prestige with 200k+ archers (possible drop'er, tho it could be a smart player)
under 300k prestige with hella amounts of cav or seige engines
Players who used to be in a Top alliance and are now lower lvl prestige
Top alliances dropping down the ladder on prestige but retaining member lvl's
