Number of listenings disappears

Hello,
I've noticed strange phenomena on my account since my subscription :

• the number of listenings (of the music I create and post) disappears. Can someone erase his/her listening?
• some likes appear while there is no additional listening number on my account. How can someone like a music but not listen to it?
• Are these things happening because someone stole my musics and put it somewhere else ?

The number of listenings are dropping dramatically, as the number of followers, while my friends are listening to my musics.

Thanks a lot for your help, I really don't understand what's happening on my account.
