I agree with a limit. Unfortunately, there always seems to be that one or two people who try to take advantage.
Could there be a way to increase that limit, though, for people in need due to exceptional circumstances? I am thinking along the lines of a severe flood or hurricane/tornado or fire that causes catastrophic damage and the gardener is starting over, again. I know that I found a lot of solace in my garden after the Northridge earthquake but I was very fortunate in that, while my home suffered major damage, the yard still looked good (what can I say? I always try to see the bright side - even in the worst of situations). Or should something like that be handled separately (outside of seedpacks - like a site-wide call for donations but then, I guess, that is a completely different topic -lol ).
Anyway, I vote for the limit, also
