Call out the hypocrisy, Parrish. Let 'em know. xD
There are so many people on this site who do that, it's not even funny. If I were to call them all out, just my one post would take up a whole page, and then some. Luckily for those thirsty little virgins, I am not that much of a jerk.
Honestly, the vast amount of thirsty people on the internet in general does not surprise me. To me, the fact that one must resort to that is beyond pathetic for me. Excuse the generalisation, but I do feel it applies, especially for a manga forum: Anyone who has to resort to constant flirting online with another person, probably lacks the attractiveness and social decorum to be able to attract someone offline. It really isn't that hard to connect with someone on a deeper level offline. There should be no reason to fall in "love" or hopelessly flirt with someone online. And on a manga forum, no less. When I see guys who do that, I laugh at not only what they say, but how pathetic they seem to me.
Like Hipster Madara stated, in the case that a guy would attempt that with me, I would generally ignore him. However, if I am bored, I'll "humour" him until I get bored again. In that case, I'll just go back to ignoring him as normal.
