my way around items leechers with my lv 90 sorc is make a huge herd orb/static/nova them and try to leave like 5 standing, then they get any item leechers hu try to run in while i collect the stuff, by themn my TS and lv 90 barb merc with a AmnAmnNef 274ED CCS and shaft has wasted the remaining cows. i dont get low lvs stealing my items, i get sum other sorc or java run in and grab em, but i usually get nick sum back off them at sum time, so its not to bad. high lv leechers are worse then low lv, them not scared of cows.
my otherr pet hate is exp shrine stealers, if u r standing next to a shrine it is yours, others should respect that. i ****ing hate them more then item steallers.
