I am guilty!! I am a autofollower! lol
It has it's pros and cons. First of all it depends on your business time and your niche. Because I am a 1STOP Business Shop my services are for everyone which means that I am not limited to who I provide my services too.
However for my clients I do not recommend auto following if they have a niche or service that is not for everybody.
So being in the social media certification course I know that you should follow people of value to you and your business. Do I recommend autofollowing to VA's? Yes only to those that do not have a niche, for instance if you are a REVA makes no sense for you to follow everyone.
I personally don't have the time to go through every profile and see if they are a fit so this makes it easier. Think of it this way: If they can't use your services chances are they know several people that could. If you already have a full client base and don't want anymore then it makes no sense to follow everyone either. Think of the extra profits if you start subcontracting work out.
I do not decline any work and subcontract out all the time and the revenue is awesome!!
Just my 2cents
