Lol no, I don't follow everyone that follows me, but that doesn't mean I hate the followers that I'm not following. I do a thorough background check on each person that follows me. I see if I like their questions or their comments/opinions etc. I like to make sure they're not weirdos/pervs/creeps, extremely bitter and negative etc. I like people I can find some common grounds with, that post funny or intelligent things, have good standards/morals/values and just overall fun, kind, interesting people.
It could mean that. Or it could mean you just don't interest her. When I follow someone it's because I've seen a few of their posts and I'm interested in what they say.
If someone follows me I check out their questions and opinions. If their posting history gives me the impression that they're just looking for cheap thrills I block them. If I find their opinions interesting, either on their own or as debate fodder, I follow them back. If I get bored looking through their history I don't follow them. It's not that I don't like that person, I just like to keep my notifications streamlined.
I have 547 Followers, @GoldCobra, and Moe that Come in Every day. However, if I feel it is Not a good deal, I will Decline to "Follow" because I will Know in my own Heart it is a Mistake from the Start. I believe with No Follow, she is Hinting to you. Good luck. xx
