errr, i have to take a stand for those "stupid" and "low IQ-stupid people" and "isn't very smart in the head" buyers cuz i was one before.

it was back in the days when i didn't know where to get English-subtitled dramas and eBay was the answer. one of the few dramas i bought include Jem's 'Loving You'. i still remember watching that series and seeing this watermark floating around on the first episode in the water scene saying "You have been cheated" or "Do not buy or rent this" and "Go to this channel" etc. and to be honest, i wasn't angry that i bought it cuz i didn't know anything about fansub at that time... cuz maybe i thought it was the seller that did the fansubbing or something. then of coz, i got more knowledgable about where to get English-subtitled dramas and seeing the drama that i paid so much for being freely distributed was when it irked me. in short, those watermark encodings really works.
okumasama: "Put a big "NOT FOR SALE" all over the screen" is a good start.

that example pic was pretty funny. if the seller/profiter tries to sell them again or just take the subs and transcribe them, you gotta give them the credit for wasting their time to download or buy the raws and get the subs and encode them and burn to vcds/dvds.
and plzzzz, don't pause or stop your releases... i dun wanna be blamed for the cause. besides, this is not a first time as kamui6 has noted. here's some solutions i can think of:
1) advertise about d-addicts, jtv, fob, kdrama, etc everywhere so more ppl know about our existence
2) like many fansubbers have done, encode the video raw with a watermark.
3) have a place or thread here where people can share their trade/distro links so even if a leecher misses a series, he/she can always trade for it or pay for it for a small fee or for the cost of media and shipping. (note: actually distros aren't that bad if the fee is small)
tailchaser: thanks for saving me the trouble of looking for links and info on reporting the seller on eBay. but yah, reporting to eBay might not work cuz it's hard to tell if the seller is selling real or fake stuff if you weren't a fan of fansubbed dramas.. and since the seller listed the dramas in DVD format, it eludes one to think that the seller is selling real stuff. and if the seller is not lying, they are located in Columbus, Georgia (GA).
LittleGreenGrasshopper: your post was well-said except i dun agree with the older generation thing. usually the older generation people are either not interested in dramas or they have the money to buy the real thing from YesAsia or something.
