There are probably hundreds more, but …
There are probably dozens if not hundreds of reasons some people on Twitter won’t follow others. Here are my Top 10 reasons.
I won’t follow you if …
1. You don’t have a bio: There may be a good reason, but I can’t imagine what it is. It takes 30 seconds to say something about who you are. The same thing goes if you don’t have a geographic location. It does not need to be specific: city and state or city and country will do just fine. Of course, if you have something to hide … that too is reason enough not to follow you.
2. You don’t have an avatar: The Twitter "egg" avatar just tells the world you haven’t made the time to get a small picture or symbol out there … or maybe you have something to hide.
3. You have been on Twitter for less than a month: Unless I can see a history of activity stretching back at least a month I suspect all Twitter accounts to have a.) hidden agendas or b.) be the accounts of people not fully committed to being part of the Twitter community … yet. I’ve been told this is hard on newbies, but I know from experience that too many newbies set up an account, tweet a few times and then go silent. (Of course if I know you in real life, that's different.)
4. You don’t tweet at least once per day: You don’t have to tweet every day, but if you’re only tweeting once or twice a week the chances are I will miss your tweets and we really won’t interact at all. So why bother?
5. You have nothing to say or share: We’ve all seen the accounts where people build large follower numbers and in three months on Twitter have only tweeted a few dozen times to let the world know “It’s raining here now” or “Just made a PBJ sandwich.” Really? Is this adding value to anyone? Yourself included?
6. You follow way more people than follow you: You may not be a creeper. You may just be desperate to build a large online following. Either way you scare me.
7. Your Profile reveals you are mostly there to sell: I get stuff pushed on me in plenty of other ways. I don’t need Twitter to feel like a selling channel.
8. Your tweet history is full of self-promotional words or links: If “you” are all about “you” and the things “you” want to sell or promote, then “you” clearly missed the memo that Twitter is supposed to be a “social” medium. “You” don’t need me to follow “you.” All “you” really need is a mirror so you can admire the view.

9. You are promoting porn, gambling or other vices: ‘Nuff said. If I wanted this stuff I’m pretty sure I could find it on my own.
10. You are a business and only ever tweet about the business: As much as you love your business and think everybody else should too, I’m sorry I just don’t care. Having said that, I will admit to connecting with social causes and the organizations that support them. That at least seems more in the spirit of social media.
