I also abide by fairly strict code of conduct / moderation policies when writing on certain platforms. If I don’t abide by the community rules my posts can be flagged or even my account banned.
Paid writing is absolutely a trade, so I can’t see how any policy that sweeps up moderation can’t also equally apply to comment writing.
The government has a nasty habit of taking a concept like “work” or “income” and then applying it to literally everything so that they can regulate and tax literally everything. To the point where the IRS had to define specific exceptions for family chores lest they be deemed as barter and requiring the payment of payroll taxes.
Luckily in this case we have the 1st Amendment which should provide a pretty strong defense against any attempt to limit basic community social activities and the necessity of moderating those interactions.
Despite the fact that [I would hope] my comments on HN accrue significant value to the HN site, and that those comments are indeed work of the kind that some people even get paid for, my 1st amendment right to post here should override the interest of the State in establishing minimum wage requirements. Would love to hear a constitutional law scholar’s thoughts on this!
