I use the
Spoiler Free page at MotoGP.com as my start page for that site.
That page works fine - it indeed doesn't spoil anything about the races - but the layout is very irritating. The buttons are way too large, so that on a 1920x1080 display (my laptop) you cannot even read the text without scrolling.
This Tampermonkey script resizes the buttons to something useable - see the examples. You could play around with font sizes etc. to optimize it further, but this is good enough for me.
