So I just issued an infraction to a member who was spamming the feed with videos...
I check the activity feed again and any other posts and comments by this user were gone.
First of all, I like to say that if it was meant to keep a user from using the feed, then...that's fantastic!
The infractions don't explain how it limits the user, or how it goes about it. I really think this is necessary.
When I issued the infraction, it was suppose to last 7 days thinking it was something view able to everyone, but when I had seen that all the user's posts were gone, I changed it to one day , as my original thought was it was just something that could be seen on their name or profile, with the inclusion of a message and reason for issuing the infraction.
Edit: I do see now that a "# of infractions" shows on their profile. It wouldn't be such a bad idea to attach it to their name outside of profiles, and on the user pop-up.
