GenKitty said: 'Stop following' works for the public forums. Campaign forums, however, can not be un-followed and all members of a game will receive notifications of all postings to their campaign forum. In this case, the only real way to "un-follow" is to leave the campaign. If your campaign members are particularly prolific about trivial things, perhaps suggest to them that their discussions might be better off in a Skype or Discord group (where you can safely ignore them/turn off notifications).
