I've already opted in to receive messages from agents I have chosen, via group notice and scripted object subscriptions, with offline messages sent to my email address. Now, it seems that anyone who owns a modifiable prim I have created can spam me with an email every 20 seconds, simply because I have created a prim in the past and have offered a recipient permission to modify the prim. Worse yet, I see no opt-out options. All other messages generated by SL residents and forwarded by LL to my email are on the opt-in basis I mentioned above. This is NOT an opt-in feature, and with no opt-out I can only see the potential for abuse, and I cannot see a good reason for the feature.
