Someone else posting with my profile?

So, on two or three occasions I've checked on my profile and found that someone else had posted in the forums, who wasn't me.
.....

I'm not sure if I've been hacked...
What's to gain? In an MMO, you hack someone's profile because you want their items, gold, character, whatever.
I'm practically a nobody on the site, so...hacking my profile seems...useless.
Not to mention I just closed any possible security leaks in my profile and made my password even harder to figure out (Not that it was easy in the first place).
Also I don't think it's the same person posting (the two posts I know about felt very different from each other).

I also don't think I've been keylogged or someone hacked into my computer rather than a profile...because my accounts on other places are fine, it's just here.

One of the posts said something like this:
"I accidentally logged into this poor user's account or is this some kind of default account or something?"

Something like this happen to anyone else?
I looked around trying to see if someone else had the same problem, didn't find anything so I thought of just posting it and see if there's an explanation.
Oh and if I posted this in the wrong spot, I'm sorry, please don't kill me. :(

are you the only one using ur pc ?maybe you forget to log it out and 1 of your relatives use it?didnt experience something like that since i joined fakku

It's not you or your pc. There is a bug that signs you on to someone elses profile. However, for some weird reason this bug is only affecting users that are Lurkers and have Low post counts. Yes it has been posted before but normally by the people that get signed onto the wrong account. And you placed it in the correct section.

And Ichiban16 the reason it is not affecting you is cause you are new to fakku. You only created your account a month ago. This affects Lurkers that have been here for about a year or more with a low post count.

OH lord, i had best post a lot more, to avoid this :o
(also secretly want to join in on the waifu thing next time)

Like what HIM520 has mentioned, I believe a bug might be the cause of the problem. Jacob and Unpantsu should be aware of the problem and I am quite sure they will rectify it soon enough, if it isn't already the case.

However, if the problem persists, more measures may have to be put in place.

-Trust me man, my relatives aren't even aware that I'm the one who fixes the computer when they mess it up. :/
That and I've got a separate profile from them, there's no way I'd make such a rookie mistake. ^-^a
Granted, I made that mistake a LONG time ago, when I was still new to the world of the internet. Not anymore though.
: )

-Odd bug...so...I guess I just have to post a lot? o_O
Either way, my question has been answered.

yeah i got shoved onto this account for some reason too. every time i go to the homepage BAM it's there.

It's either some weird bug or something jacob set up intentionally to give anons something to post with.

O_o
That's my account.......

This is a very annoying bug. :/
