It will only affect your status if you decline a booking REQUEST - not an inquiry..... even if they write requesting info on dates - as long as you reply once - with a short saved message saying - no soliciting and I have reported your profile to Airbnb' and you should report/flag them. And if any of them are actually booking dates - that means they have paid! So I wouldn't worry about it.
ps please get a profile pic - it not only is respectful but is a requirement from Airbnb.
Best Wishes.
