Ohhhh boy that brings back memories. You would PvP in Hardcore mode and each person had a 'Mule' friend in game to pick up their items. You had to make them pick up an extra item that would cause them to automatically drop all items stored in the corpse. Good times. Did it myself but never for money. I was just an asshole kid in a group of asshole friends who did asshole things on Diablo 2. I think the bow you're referring to is Windforce.
it was just a rare very fast bow... i think windforce was a thing that came later. this was still just months after release maybe... early spring '01 -_- at that time, speed 'stun lock' bow zons were dominating PvP, and everyone wanted bows with the very fastest speed more than any other attribute, so the fastest speed bow in the game at that time was actually only from Act 2 in the palace... some short bow.
so, rare bows from there with the fastest speed but also awesome stat bonuses were super rare but also dominating pvp because you could spam guided arrow (I think... one of the bow attacks caused like an animation frame lock at the time) and basically just stun lock people. the damage was totally irrelevant they couldn't move. i think windforce came later when zons moved to... raw DPS where speed didn't matter (?) back to multi-shot maybe.
but yeah I think we started 'inventory exploding' or at least were one of the first on US East to do it... at the very least, no one was really doing it, so maybe my friend heard that someone else had figured out a way to do it, but i still remember the first time we tried it and it worked lol was like a 'eureka, gold!' moment ;p never used it in HC though.... we PKed in HC mode but the 'inventory exploding' we started in regular mode. we were still learning it so sounded kinda scary to risk experimenting with in HC haha
we used to do a lot of dumb stuff..... Telekinesis was another: we created a thing called 'teletrading' where we'd say we really wanted some 'blue rod' I thought I saw and it was Ume's Lament, so we'd make a offer 'too good to not consider' like SOJs, but say we really wanted to see Ume's on the ground (since early on no Necro would trade it, so equipping was not an option) first to see if it was blue. They'd put it on the ground maaaaybe 5-10% of the time, totally unaware probably that Telekinesis even existed yet (we're talking the first 2-3 months after release), and a quick zap later, a new Unique =p It failed the vast majority of the time but I used to get a pretty decent unique like a Ume's Lament, Bonecrusher (for low level barbs/pals), that necro skull helmet, etc once maybe every 10 tries. nothing that valuable tho the game was too new to really have certain scarcity demand yet, uniques lost their value pretty quickly after 1-2 months.
actually i became a bit of an 'honour' pvper after that (in MMOs at least) just because i kinda started to feel bad how many people's games i probably ruined -_- not that most MMOs allowed for D2 style griefing, but my close buddies were pretty famous in DAOC for griefing, and I ended up taking a pass on joining them in lieu of trying to 'help' my realm o.0
anyhow if I remember right, Blizzard patch both 'inventory exploding' and telekinesis eventually... we really were jerks q_q
