I frequently witness such attacks on noobs and aspiring rpers alike from those 'jerks'. You get it everywhere. Nine times out of ten I take the poor guys side since I have a small amount of credibility and a number of friends since I keep my nose clean and watch my P's and Q's. I myself, I'm usally on at least once a day, but not for hours on end and never to just sit there and wait till someone says something. Although, my grandmother thinks I spend way too much time on it, but it so addicting, I agree. There have been times when I think I'll give it up, but then I find that really awesome rper that I want to get better than and I rp with them for a while to pick up their skills. Kinda like Demon Eyes Kyo of Samurai Deeper Kyo, hence the one character of mine, Katamara_Mibu ^.^
I'm no where near multi para posting, but I'm a para poster though at times they dwindle down to a few lines. Most of the people I rp with agree on quality not quantity, but it's still awe inspiring when you see a good multi para. Someday perhaps, someday ^.^
If you ever feel the itch to give it a swing, even for just one go, give me a holla out ^.^
