I literally just answered this a few posts ago. You used to be able to reduce the earnings, Trump removed that ability if it's a Hobby. You'd need to treat it like a small business.
Yes... they have. Multiple times. This is inherent with the management of hobby versus small businesses.
If it's consider a hobby, and not a small business, the 5k expenses is no longer realizable, and you're taxed for the full 6k income per Trump's reforms. Previously, and post 2025, you'll be able to realize the associated hobby losses associated with the revenue that's generated.
Previously, 9/10 times, it was considered to net out, because hobbies are expenses. However, with Trump's change, it's a new revenue stream that's untapped.
