If this were the case then even cooking your own meals at home would be questionable without the relevant work permit. Whatever the law actually states, i believe you are at very minimal risk if doing things at home only and for no financial gain.
yes agree and there's usually no shortage of unhelpful advice to go along with it.
That said, this particular question would have been easier to ask google than here. You're a good person for clarifying the facts for the OP though π
