Deleting deadbeat waterers/gifters
I don't know about samizmyne, but I also delete; and my former neighbors DID water, they just slacked off... And then stopped completely. But unfortunately, they still get watered by others, so there is zero incentive for them to be courteous.
*I don't want anyone to think I'm a strict water or gift watcher that just waits for people to not water or gift once or twice. (Mwaahaaa hahahahah! - j/k) I only delete after I'm positive they are gone and not coming back, or just can't be bothered to reciprocate.
