It used to be my favorite messenger app, but: 1. It crashes my less than a year old Samsung Galaxy phone constantly and places it into a forever boot loop, so I had to uninstall it, and 2. Even when it works, the fact that they creepily monitor and block messages on their own apparently bigoted and biased discretion based on an ever changing and inconsistently applied user policy. I could see doing this for crimes, but for discussions with friends and family? Wow. Bad policy.
