Every time you lend your name to something, you’re co-signing its consequences.

Association transfers in both directions, and nobody asks permission for the second one. Put your name on a group, a post or a project and you receive credit if it goes well and an equal share of the fallout if it does not. People later will not separate the degrees of involvement. They remember who was on it.

Before signing on, ask whether you would be comfortable being asked about it in a year by someone who assumes you were fully in. If not, stay out or change what it is. Half-in only exists in your own head.
