This may not the right forum, still I would like to raise the issue.
I was in contact with Dave in July and learnt that it is not possible to block other persons from following your profile in the developer community. He said you would look into adding the feature in later versions of the community software. Will this be available in a near future?
From an integrity point of view, it feels a bit strange that I can not decide for myself who I want to be followed by or not.
