Regardless of the spelling hopefully Gumtree will soon take the same route as eBay did about a month ago (very low key mind you) and ban this sort of junk.
Tellingly, eBay did not issue the ban (at least publicly) due to any particular standpoint - they, like the charlatans are happy to make money out of it - but rather because of all the difficult to resolve complaints about the 'services' not working.
