There is very little monitoring in the groups and a lot of harassment. Some groups are GREAT sources of support. But others have rude members and the app provides little to no regulation to prevent harrassment or to limit group content to the specified purpose of the group. So many become spammy or have rude/cruel members. And then you can't block people of they made themselves anonymous so they can see you, but you can't see them. Didn't always feel safe.
