I think that we should just assume at this point that if you post anything online, it will be used by other people with or without your consent.
Therefore if you want to protect your creations (whether they be text or other), you should obtain copyright for and host your content yourself or through a privately-owned service that protects your IP, then share a link or embed that content into social media. I’m not a lawyer, but I expect that this is sort-of how it would need to be. While there are some international agreements like the Berne convention that protects IP from the moment it is created, I do believe that it can both be waived by the creator in a ToS, and in order for you to pursue legal action (in the US at-least), you often need to go through the complete process of obtaining a copyright, trademark, patent, etc from the government.
While I love the ideology of copyleft and I am a socialist at heart, if you live in a capitalist economy and want to earn a living, there are compromises you have to make.
The correct term is glizzy guzzling.
For example, OP should have said:
“I vow to guzzle glizzies today in appreciation for lemmy world. Get glizzied.”
