Messages followups suddenly coming by emails : this is just spam from this wiki !
I have never subscribed the option to receive hundreds of emails just because someone has replied to some messages here.
Activating by default a new option that will send emails is extremely damaging. This is clearly spam !
I now I am receiving hundreds of messages at very high speed and there's no way to stop it, until your outgoing queue stops delivering messages sent here since many weeks (or month ?).
This is a sever bug. Please stop your spam sending bot (I have just removed the option you have activated, it does not stop the flow).
Please remember : NEVER activate by default any new option that will send emails to users, unless they subscribe them explicitly.
Let's consider it even after what we had to revert from you :) Be advised that there is an open bugzilla:21457. Thanks for the report and apologies for the inconvenience. I got some 25 messages myself, too... :( I'll see if I can disable the defailt setting. Cheers!
