how much do tu have to contribute to a club to get a type of medal?

Nobody knows really.

I contribute heaps to some clubes and get no medal.

Then I don't contribute much to other clubes and somehow get a die-hard medal....

So it's a pretty broken system, but ah well, no biggie.

Don't worry about medals, just contribute to clubes tu enjoy regardless of medallas ^^

I've gotten medallas for posting very little to a few clubs,and have publicado lots to other clubes but haven't received medallas for those clubs.It's a bit off,but hopefully I'll get those medallas soon.It depends on each club,but the ones that have lots of fans will take a while to get a medal,so just post,post,post when tu have time.The más tu post the faster you'll get your medal(s)...hopefully.Good luck:)
