You and all the other anti matchmaking people in this thread won't need to worry about that because it won't affect you one bit.
And it is not nearly as easy as you suggest to get a raid team sorted via this or any other forum. It might have worked for you but I've yet to get in in an OCUK raid despite posting numerous times (although tbf I only got to L27 just now). You need to schedule it in advance and there's too much sitting around sending invites and waiting on people, etc.
Thats a load of crap. You clearly havent tried the bungie fireteams forum. I posted on there last week, a quick intro of what i wanted to do mission wise, console, time and other specifics (level 27+, mic, english speaking, available within next 15 mins) that were needed. I was doing the nightfall so needed 3, yet i had 8-9 people add me as a friend and message about playing. Theres plenty on there.

My experience of the OcUK clan is that I start the Destiny companion app, see there's a message from someone two hours ago asking if anyone wants to do the weekly heroic. Well as it happens I do but that was two hours ago and I dunno if that guy has done it already or given up if he's even still online.
