What's up with all the "digital marketers" on this site?

For about three days now, I’ve notice a lot of new accounts on this site that follow the same patterns: most have Indian-like names, most have a profile picture of a random Indian-looking man, most describe themselves as something along the line of “I’m a professional digital marketer” they may also contain some other profession like freelancer, and almost all of them don’t post anything on here. There are no link on their profile, so I can’t flag them for being spammers, but it’s just odd that there are so many accounts that look the same, and they all pop up at the same time in a row. They don’t seem to promote anything, so I don’t know what they get from doing this.

Do you notice that? What do you think?
