Unless you are trying to be antisocial, you would say...

Is there anyone who wants to practice English with me?  Please don't hesitate to contact me.

Please don't bother to message me..>>>>>> please text me freely. Don't hesitate to send a message to me.

Don't bother me =  Don't talk to me. Leave me alone.

So, as Jerry and Miriam say, nobody sends any messages to you. Be careful.

I hope this helps you.  Good luck! 

One more thing, You can go to the section of finding partners. This section is the discussion room. but you can see nice people in this room anyway, enjoy it!
