Lots of these on Ashley Madison and Illicitencounters. Just have to read the profiles. "like a successful man, enjoys fine wine and dining, prefers the finer things in life, generous, enjoys pampering and giving gifts", so the list goes on.
Before AM got hacked, was corresponding with such a lady by email and phone calls. Led her to believe I was the rich guy she was looking for. Although she lived in North Essex, insisted we meet in London to do some shopping ( guess who pays?). Anywhere more near me was met with excuses, like "might bump into someone who knows me". Oh yer, 20 miles from where you live!! Went along with it to the point of arranging to meet at Bond St station. Did I go? Hahahahah. Never heard from her again.
