When a pinned topic has a total reputation count of -5 (-6 but the last one was me, so that doesn't count!), and it contains about 10 pages of people saying the topic shouldn't be pinned, it is quite clear that the topic should in fact not be pinned, regardless of what forum section it is in.
If the user, Robinskie, had not been driven away by the fact that the IRC channel more resembles an anti-children channel (see IRC channel description) than a GameMaker Community channel, he would have waited longer, and users, myself included, would have been able to answer his question.
This topic is directly associating the IRC channel with the GameMaker Community, which - whether you like it to be or not - is associated with GameMaker.
Since it is a pinned topic users will assume it is endorsed by the GameMaker Community and its moderators and administrators, and that makes it an indirect representative of the GameMaker Community on the IRC network.
It should not be pinned.
I have voiced my opinion, and I will likely not respond to any posts past this, but I will read them.
IRC is often a poor choice for technical help.
And regarding judging the value of this particular pinned topic by its reputation. That's just silly.
This topic was also created during the time frame where "bots" were negative repping topics. Look at who has negative repped this topic. You will see an overwhelming number of the negative reppers are indeed said bots. Had it not been for them this topic would be in the positives.
So, if one is going to use reputation as argument for a topic and its value, knowing that actual GMC members have really given this this topic a positive rating, then you have to then argue that the positive reputation this topic really has justifies it.
Having said that, I couldn't give a crap one way or the other whether the topic stays pinned or dropped off into oblivion. The few times I'e gone to it< I see a bunch of idlers or non-sense.
