Is that you were asking around OOC for help finding your sleeks. So you're perfectly ok with using OOC knowledge to benefit your character, but if someone uses OOC knowledge against you, you have a problem? Hypocrisy, much?
And that's not even to mention the (very likely) possibility that you were found entirely in-game anyways. It isn't like you were the first person ever found in the Frozen Wastes, after all. People go through that area and the areas leading up to it fairly regularly. The person who attacked you is fairly well known, and a lot of people would be willing to help them.
Plus, you're a douche. And you've outted yourself as this character. So everyone that thinks you're a douche would have an OOC reason to feed Drissa information IC, regardless of if they found out about your location on Discord or saw you IC. That's a situation entirely of your own making, so you should suck it up and deal with it.
