HMRC monitor all sorts of advertising forms, for all sorts of businesses and I have heard AW is just one other place.

Basics of the answer to your question is this, those in receipt of means tested benefits have signed an agreement that says you'll advise DWP/Housing benefit/Council tax benefit if your income changes and that is your responsibility. You can still register declare your earnings and probably not be liable for any tax especially if you have some expenses to offset. The benefits system is from what I hear these days and experienced many years ago, very complex and that is one reason I keep well away from it.

I'm a verified member on AW and my private pictures show my face. I am thinking of changing my profile to say I am not escorting. I would have to ask people who have given me feedback to remove the feedback if possibe.

Hiya figure what you want to do, as to benefits be EXTREMELY CAREFUL,THEY ARE NOT NICE PEOPLE!!!. You need to declare asap to the dwp. These days they check with a fine tooth comb. Save a bit of money and come off it,( especially if you do not have kids or such) it is more pain than its worth (what they provide peanuts, you can not support yourself , with so much angst,rudeness and aggravation  and absolutely no tangible support. Again if you do not have kids come off it as soon as you can and in the mean time declare your income.

When you sign off finally, declare your self as self employed and depending on what you earn you can get help/part rent and maybe working tax credit (of course declare everything honestly cos they are not kidding around,they even now come to your house to check facts !!)  Best of luck
