If I worked for the HOA and I saw this I would try to figure out if anyone knows I saw it. If not, I would ignore it. It's technically against the rules but OP seems to be doing a good job of managing it, and I doubt I could apply a higher standard to the rest of the units. I'd wait for a resident to bring the issue to me, which would hopefully never happen.

If I managed a ritzier condo complex I'd probably do something about it immediately rather than take a wait and see approach.
