Bookmarklets

[Marvash Magalli]

Are they allowed? Only found one menton of them here, something made by@Luki a long time ago.
I just found out about them, and bruteforced my way into making one that hides entered raffles.
I know nothing about Javascript, so sorry for the dumb questions:
1) Is this against TOS? Afaik only scripts/macro that give you an unfair advantage are forbidden
2) Could the use of bookmarklet trigger the auto ban triggered by scripting?
3) Can I share my bookmarklet here for everybody to use?
