As us accountants have to fix up the mess from incorrect advice, we get a bit touchy about non-helpful advice.
Oh, spare a thought for the accountant with the bleeding heart
I could say the same thing about my profession where I have to 'clean up messes' left by bankers or other incompetent brokers. I don't claim to know everything either, but you make it sound like accountants are the arbiters of good advice and I just don't accept that.
Yes, people here should talk to a professional about [insert tax/finance/accounting/legal question]. Simple fact is people can't rely on this forum 100% for proper advice, when you can't 100% rely on a professional that you pay to do so since even the professionals get it wrong. Is bad / wrong legal/accounting advice an excuse in the government's eyes? Hell no. Ultimately that little disclaimer at the bottom of every tax return that my accountant does says that I am personally responsible for any errors in it. So please stop the ridiculous assertion that only accountants know best.
