How to send automatic thanks to new followers on Twitter?
 

Hello friends,

If I say thank to my new followers manually for following me. Is there a ways to automatic thanks to new followers on Twitter?

I also want to send automatic massage but when they follow me. Is it illegal to do on twitter?

Nope, it's not

Technically, to accomplish this you'd want to use User Streams to monitor new followers in real time, then issue either a statuses/update request or direct_messages/new request depending on how you wanted to communicate with them.

Is there any official app to use as this? #Help

Is not there any official way to do this?

Even I want to know
