Find out if someone has blocked you using a 'messenger block checker'
You use Messenger and are afraid someone had blocked you from your contact list. Unfortunatly, we can't help you find out. What we can do is provide you with informating regarding what is, and what is not possible. Many websites claim they have a working blockchecker. Don't do it, they won't work and might actually harm you instead. For example, if you have to download and run a file it might contain a virus or the website might be harvesting e-mail addresses for spam. Since Microsoft fixed a glitch in Messenger years ago it has become technically impossible. If a block checker gives out any results, they are false!
However, it is possible to find out if someone has deleted you from his/her contact list. There is nothing special required to do this, simply open Messenger, go to Tools and then Options. On the left click privacy and you will find a list of all your contacts. Now right click the persons e-mail address, if delete is greyed out like shown in the screenshot below the person has not deleted you. If it is available/black you are deleted.
The delete option is greyed out, the contact has not delete you.
If you really want to know if someone blocked you just drop the person a mail and confront him/her.
