Flatmates not putting bins out

Where i am we have a cleaner but it’s our job to do the bins. Initially someone made a bin rota but it was quickly thrown out the window and people just did it whenever needed. It was originally three of us who did it since the rest just didn’t bother but i noticed now that i’m the only one who is doing it.
I decided to be petty and just simply not bother because i’m not about to be the one who deals with everyone’s **** so i let the bins get full.
Instead of my flatmates walking a minute outside our house to throw them away, they bagged them up and set them aside for a whole day till i got ****ed and just threw them out.
I know that’s likely not helped but the issue is if we don’t do it we get a ten pound fine everytime and i would rather not. It’s also worth mentioning we don’t really all talk to eachother that well there isn’t a group chat or nothing. I considered leaving a nasty message and calling them lazy but i don’t think that would make them do anything. They already leave wrappers and food everywhere, i feel bad for the cleaner sometimes to the point i’ll clean up the night before she does her job out of embarrassment.
So i don’t know if i should just be the bigger person and put up with being the one to throw away the bins constantly till i move out next year or just go on a little strike and not do the bins to prove a point and potentially get fined.
