Travis Lawson bogus responses to items for sale on CL Internet

Posted item on CL - initial price was too low, revised.   In the meantime received response from one individual (will file separate report on him) asking me to take off CL and provide way more information than I feel necessary.  2nd individaul also promised delivery of "certified" check and then would send someone to come pick up item since he couldn't come himself.  Needless to say have blocked this creep and want him reported as scammer/spammer immediately.  I can see he has used other variations of email address as well on other postings - he posts as TRAVIS LAWSON [rondiazelectronics.puerto004@gmail.com] but others have .puerto005 and Lord only knows what other addresses.  Googled this name and saw way more than I wanted to see/know.
