Hello @artemislives, if you use peakd then the list function could serve that purpose pretty easy for you. One of the list I have is for those I delegate to with either my active account or somewhat dead delegation account for new users. Once a day I just bring the list up and take a look and see if there is a post that needs a little help. I am a big fan of the list function. It is easy to add them and easy to remove them, and as far as I know people don't know if they are on a list you create or not.
Right now I have 15 list, some are for what mood I am in, like music, photography, writers, others hive tool/knowledge like witness, curators, developers, and some are just general like fun and contest.
None of my list are real extensive, but I am constantly building them as I remember to add people. Communities can be added also but you have to do that manually since there is no Actions button on community pages.
