Well, I guess what I do would be considered stalking, I have an urge of some sorts to know everything and gather as much information in an environment as possible, in that way I could identify and adapt to any change that is present.
In the forums, I have honestly clicked on the profiles of a handful of people, I also look at activities on the 'Users Online' Feature quite often. It may be invasive but I'm not going to misuse any info, and it's no secret anyways.
I also gather information irl, don't get me wrong, I don't follow people around like a creep or avoid getting caught eavesdropping, I do it on a semi-conscious level. Whatever I hear and even emotions that are emitted would get absorbed whether I like it or not, which could either be beneficial or distressing.
I don't embrace my surveilling habits unless I have a clear motivation that is justified, I'm more a monitor than a stalker in my opinion. But gee, I remind myself of Nineteen Eighty-Four sometimes :u
