well I'll answer this with a question? how can they follow you if they don't have a twitter account?if you mean if they're not on, then you can protect your updates from your settings and that will let you accept or decline any new followers. you can also go to you followers and block any that you don't want. hope this helped!
If you suspect that you are being followed by someone I suggest you speak to your local police department and see what your options are.
Go to your home page...under where it says followers, click on that and it shows you all the people following you!!
The only way to tell is by looking at their profile to see if they are currently tweeting. There is no "online" status or symbols.
go to their profile and if the message (direct messages) option is available then it means they are following you.
Go to your following page.
Click on their profile and then on their "following" list on the right hand side of their profile.
yes
It is impossible to send a DM on Twitter to someone who isn't following you. The user has to follow you before you can send them a DM.
At the top right hand corner it tells you how many people you are following and how many people are following you. If you click on those that are following you, they are in order of when they started following you. So, the one at the top is your most recent follower.
I think you can follow someone on Twitter if you have 900 K people already. It should not matter how many people you are following or who is following you.
It means "Someone I'm Following"
Someone that you are following would have "retweeted" the tweet.
On Twitter, you can invite your msn contacts to join Twitter.
i think so
One can do a quick name search on Google and find their social link including twitter.
Go to their profile and click "block"
There is written up on the right "Find People".
