One thing to consider is hashtags. Each Lemmy posts automatically gets a hashtag that’s identical to the community’s @ name (so, this post has #canada). It might be worth poking around the Fediverse to see if there are existing hashtags that might make sense, and to give the communities those names, just to extend visibility beyond Lemmy.

Treason

(2) Every one commits treason who, in Canada,

(a) uses force or violence for the purpose of overthrowing the government of Canada or a province;

(b) without lawful authority, communicates or makes available to an agent of a state other than Canada, military or scientific information or any sketch, plan, model, article, note or document of a military or scientific character that he knows or ought to know may be used by that state for a purpose prejudicial to the safety or defence of Canada;

( c) conspires with any person to commit high treason or to do anything mentioned in paragraph (a);

(d) forms an intention to do anything that is high treason or that is mentioned in paragraph (a) and manifests that intention by an overt act; or

(e) conspires with any person to do anything mentioned in paragraph (b) or forms an intention to do anything mentioned in paragraph (b) and manifests that intention by an overt act.

Basically, the US government would atually have to use force to overthrow the government, and we would have to be able to prove in court that Elon participated in those actions.
