I am currently being harrassed and accused of plagiarism but am unable to report it as your function to do so does not allow me to, I am repeatedly told to try later.
Judging from previous comments and threads, harrassment and bullying is something that you consistantly fail to deal with when bought to your attention. This is a serious issue and could result in legal action if you continue you to knowingly allow it on you platform.
There are several places on FamilySearch where you can report abuse. I'm not sure where it is telling you try again later. This article tells you the different places you can put in a report.
