Hi, Keiths.
You may disable it here:
Backend -> Components -> JomSocial -> Configuration -> User points and disable point rules for avatar and cover upload.
Then those activities will be not displayed any more...but also users will not receive points for them.
Hi, Keith.

Hi, Keiths.
Yes, I still see old credentials that doesn't work.
Please, edit your first post just like I described above.
HI, Keith.
I just created a test group "JS test group" - uploaded avatar and it wasn't displayed on group stream.
It seems to work fine.
Please, note that avatar upload posts will not disappear after you disable points rule - only no new post will be created.
