bestcoverletters.com é seguro?

They are claiming to help people write cover letters but with very poor examples. I looked at several teacher cover letters. Most of them had spelling and grammar errors. For example, one example was of a teacher who had experience teaching "grammer." Their list of "partners" tells me that the website just is a scam to make money. Most links have nothing to do job searching and sound sketchy. This disappoints me that someone would take advantage of people who are trying to seek help in finding a job.
