I just recently hopped on tf2center to see if any of my friends are playing, and I saw something I haven't seen before: instead of the usual 6v6 or HL lobby it was a small HL heavy opening. Little did I know that it's a substitute request, and that it will *immediately* make me join the game when I so much as click it. I clicked it half-accidentally-half-curiously (as in "oh, what is that, a new lobby type?") and then when I realized what happened I closed TF2 ASAP, as I didn't actually have time to play at that point. But from tf2center's point of view I declared to play the game and I didn't, so I got reported and now my profile says I'm unreliable.
This is a horrible user experience; I was used to needing 3 (or 4) clicks to actually join the lobby and start the game, now I press one thing and I'm suddenly commited to it? I totally didn't expect that to happen, and I believe my reliability has been inequitably lowered.
