Listing "memberships" on academic CV I have seen people listing "memberships" on their CV. Do you have certain rules of thumb for what to list? I have some myself, which are basically memberships that have happened automatically, when I have been invited to give talks - like, come give a talk, and please join our "board of associates". I don't do any work in those roles, and listing them feels a bit like CV padding. I am in the beginning of my career (first post doc).

What is the normal practice?
The general rule is "if you don't want someone to ask you about it, don't put in on your CV." Including such memberships is still standard practice for many as they signify both your involvement and willingness to continue to participate in your field. So, don't think of these memberships as padding, think of them as opportunities to highlight your accomplishments - unless you really can't find a positive way to discuss these memberships, in which case they should not be included.
