To be fair, a lot of people probably got into this situation on an equivalent recommendation.

I agree with you, but context definitely matters here... With all the dominoes starting to fall, there is nothing wrong with moving funds out of exchanges or to a temp address. This seems equivalent to going cash in the equity markets as a hedge. I would go even further and claim that it would be foolhardy to not take this random Discord advice if they haven't already figured it out on their own lol.
