Is it possible to restrict certain users from deleting note entries in the Feed section?

Question

Is it possible to restrict certain users from deleting note entries in the Feed section? Need to restrict some users because we are having problems all the time with this.

Answer 1

There may be a simpler method, but this is what I have for now.

Write a trigger on FeedItem on before delete and stop selected users from deleting a note:

trigger feedtrigger on FeedItem (before delete) {
    for(FeedItem  fed: Trigger.Old){
        if(fed.type == 'Contentpost'){
            //Do further checks based on profile/role/Id etc and restrict the user from deleting the note.
            fed.adderror('You cannot delete the note');
        }
    }
}

Note: You can add/ adjust type and prevent users from deleting Links, poll etc..

Refer this doc for different types of feeditem:
