Although I agree everyone should play Glitch how they want to, (an aspect of Glitch I like), I wouldn't like something that actually encouraged Glitchen to not share and not keep their public space freely available to everyone
What a fun, creative way to indicate you prefer no visitors. While i agree with Rhonda in that we don't want to encourage people to not share, giving them a way to indicate their preference is better than the current system, which is the systematic blocking of people who visit/harvest/etc.
+1 to The Cat Face for JuJus - "Harvest My Street at your Peril!" ....not MY street though, you're all welcome to come and help yourself to as many Jellisacs as you like :)
