Rubbish - fuming

[Birdy1991]

I live in a block of flats with around 20 flats. Yesterday, we noticed that someone had left three bin bags outside the door to the building. I thought to myself ‘that’s going to make a mess overnight, some vermin will get to it’.
Went out this morning, rubbish everywhere. Literally everywhere. It looks disgusting.
I wouldn’t be surprised if it was a resident, one of them leaves rubbish in the communal hallway for weeks which is really annoying and starts to smell. AIBU to leave a note on the main door to ask them to clean it up and to, in future, take their rubbish straight to the big city bins on the road? It does not take a lot of effort and we all deserve to live in cleanliness!! There’s no way of knowing exactly who it could be so can’t speak to someone directly. We live in Brighton which is supposed to be a ‘green’ city but sometimes the outside of or block looks appalling.

Also to add. I thought about taking it to the bins myself yesterday but wasn’t sure it was rubbish or if someone was going to do something with it.

Nothing to stop you leaving a note, although they may ignore it. Perhaps add something to the note saying "I did wonder if someone had a problem getting to the bins, but with no note on the bags, I didn't like to move them in case they weren't rubbish. Do stick a note on if you need someone else to take them out for you."

I think the note will be ignored. But put in the note what lanthanum suggested.

Does that resident have issues getting to the bins, why have you put up with that?

That's really horrible OP. I'd take a photo of the mess in case it's a recurring issue/or it gets cleared up in the meanwhile.

We live in a block with no lifts and all of the floors involve stairs. It’s the flat opposite us that I think it may be as they like to leave their rubbish in the communal hallway (first floor). They are able bodied.
Not sure what to do about that either but that’s an issue I’ve been trying to ignore! Recently what they’ve left out in the hallway has started to smell, though...
@lanthanum I like the idea of what to put in the note though, it’s less passive aggressive then...
