BLoodSireSpoilers are regrettable, but this is the hub of all things comp tf2: the 1 place you should be avoiding after the scenes biggest LAN. I can sympathize with trying to remain spoiler free but I wouldn't expect to go to mlb.com after the World Series and not expect to see who won it plastered all over the site. Next time waiting for the vod would be the best move.
That's because mlb.com is a website that's literally just baseball news, and I doubt they actually give a shit about whether they spoil anything.
TF2 tournaments happen all the time, all it takes is carefully wording post titles and using spoiler text to make it so that tftv isn't unusable for anyone who wants to watch the vods.
