said that coz who want to increase his/her follower ...
What good is it to send updates to people who do not act on them, share them, or otherwise engage with you about them or vise-veras? No magic awards or keys are awarded for going from 50 to 51 or 50,000 to 50,001.
Your gross number of followers is nearly meaningless in actually driving return. So unless you have a need for bragging rights, and even then picking up one or two followers at a time is hardly the way to go about it, stick to quality first.
Well i don't think any one prefer these kind of tools.Because any time twitter or any site detect it you ca be banned and your time and work become useless.So it is recommended to go for ethical ways to get quality traffic.
Twitter people will only follow you if the content in your Twitter account may be of relevance to them, or if they're interested on it.. Try to post things/topics that you think many people are interested in.. A good exercise is to follow only the pages you think the people are mostly interested in
