Be able to report those, who have blocked you
Lot of profiles are fake, catfish. There are measures that can be taken to figuring out the fake profiles during conversation, but when you're getting close to do so, a lot of times they block you before they can be reported. Same with those who provoke hate with harassing comments and hate speech. After they leave their offensive comments, they quickly block, their profile disappears and then again, they cannot be reported. The profiles should still be visible where all contact functions are disabled, but still be able to report them and attach chat history to the report.
