I hate to say it but TM15 you are part of the problem, not part of the solution.
Whilst you sort rubbish and tidy things up, the rest of the residents don’t perceive there is a problem.
For a short time let the bins be full.
When other residents realize that the problem exists, then you can rally them and move forward with a solution.
And the solution is not more bylaws, because as someone else pointed out, yo7 have to catch the miscreants
