I understand the considerations. On the other hand, let me give you the example of a project I set up: with a local healthcare institution, we set up a twitter channel with workflow using Hootsuite that enables parents of children with all kinds of problems to ask for advice from a doctor. The people operating the account are all registered MD’s. As I psychologist, I helped determine the strategy and proposition. One of the key succes factors was based upon the auto follow back. Let me explain:
If a parent is searching for a way to ask a relatively personal (medical) question about their child, you want them to be able to ask that question the moment they find you. Otherwise, the motivation passes and they will search for another option, most of the times not backed up by MD’s. Engage in action when motivation is high. So that’s whey we setup the auto follow back and auto DM. Once they follow the account, we follow them back so that they are technically able to send us a DM, which is not possible otherwise. The auto DM contains a short instruction “Thank you for following. You will be followed back so that you can aks your (personal) question in a DM”.
As you can read, this is a very practical use of auto follow back. Has nothing to do with marketing or relevance of content. Just to enable followers to send us a DM. I hope you can take this case and discuss in internally. Here in the Netherlands is was seen by the Social Media Club as the frist usage of auto DM and auto follow back that was actually valuable and not annoying.
So, for the sake of this account and the parents with questions about their children, I hope you re-enable the auto follow back, maybe with a special request form for cases like ours?
