@herrabre That all depends on e.g. relative follower counts (see there, a good use for them!).

The basic attitude should, I think, be not to blow up someone's moment of being stupid on the internet. I.e. if you respond, don't dot-reply (or whatever the equivalent thing is). If you want to spread the thing on, do so with blacked-out-screenshots rather than a direct link to the post (unless you _want_ to start a dogpile - it's sometimes a valid tactic).
