The op could be 100% right and I am not disputing that could be the case here, but I would like to say(just to be fair) that in some communities, especially in 3rd world countries, it is possible that these folks are related in some way and helping each other out. Whether it be family, lovers, cousins, roommates, or whatever. You guys have seen the image of all the people in the office working together on bounties or whatever.
Well you could be right, but can you accept that activity if it was a family, lovers, cousins, roommates etc did that on this forum? I won't.
Either they're owned by the same person or they're a part of close relative, they're doing unethical thing to "cheat" on this forum. Since there was no DT member left a negative feedback, this accusation is fine.
