Discussions about Hiring and Hiring Practices

[Docperk]

My question is in the Market Place I frequently see someone pop in and out with a post of:
"sally: hire me pls! i use the ẹfarmẹr tool from w ww.e farmertool.com" I have see other names than sally but sally I think is the most frequent. They are gone so quickly I don't think it is actually anyone and they are getting hired. Is this just a bot or what?
