I (37M) am a proud member of my neighbourhood HOA, my neighbours (22F) and (21M), moved around 4 months ago. Like a good neighbour I warmly greeted them into the neighbourhood, and kindly let them know the rules of the neighbourhood HOA. I know that when you hear Home Owners Association, you get a very negative idea in your head, but our HOA is both very reasonable and relaxed, as long as you abide by the very simple rules. Now in the first month these new neighbours managed to break nearly all of them, their lawn was unkept, they placed rubbish bags next to their bins (And may I add that extra bins are available for lease at a very affordable price) and while their dog does seem to be very well behaved they continue to walk it without a lead despite being told many time stop doing these infractions and very politely as well.

Now, after months of dealing with these things, I realised something had to be done for the sake of the neighbourhood. I knew the agreements of their lease with landlord as him and I play tennis together. I mentioned they owned a dog, and that under the lease agreement they were not allowed to own or keep a dog in the house. So I mentioned to their landlord that they kept a dog, and I may have also told him how they disrespected the rules of the HOA. In the end, the couple of evicted from the house. The neighbourhood is now a much better place but my sister told me that I it was a bad thing to do. So AITAH?
