Sports spoilers are different than movies/tv/etc. If you don't want to know you have to stick your fingers in your ears and go Naa Naaa Naaaaa! when you pass the water cooler on monday morning.
I watch formula 1 usually day of the race but always time shifted. If I miss sunday on monday morning I can't look at certain feeds or sites before work because I know it will be spoiled. With sports the responsibility lies with the watcher, not those who watched.
Bottom line, if you don't want to spoil tournament results, it's up to you not to come to pinball forums, until you watch.
