Scam Calls and Emails

About 8 yrs ago I made the mistake of posting a 4 wheeler for sale on Craigslist. I only listed my cell number. The scam calls and nonsense started 30mins after posting and got so bad I gave up the cell number and got a new one a week later. Everything from trades for work in place of money, sex solicitation, 4 fake "your kid/spouse/grandchild has been in an accident" send money for ambulance, payment/ banking verification requests and my favorite will I ship it to an adress in Dallas so they can test it before buying. They were going to send me a "wire" as collateral...
Since then Ive got a burner phone I use when dealing with the public. Anywhere I go and someone at a store or general nuisance asks for the cell #,they get the burner number.
