It's a delicate area, I suppose.
Someone asked about contracting in the UK for the first time. I gave a well received answer (currently 16 upvotes) with a bunch of details, but said that the OP should consult some professionals (accountant, tax advisor, financial consultant, employment agent).
I didn't want to publish their contact details because 1) I suspect that would be against the rules, and 2) I would have to contact them all to get their permission.
So, I said that if the OP posted an email address (temporary, if he wants to avoid spam), I would email him the contact details.
Someone suggested an edit to remove that part of my answer, I would guess to keep all info on SE, rather than in private email outside of it.
I don't feel strongly, though lean towards helping the OP, and am simply asking for clarification as to how I can best do so.
