I have a question about profile backlinks. A few days ago my site, which doesn't sell anything, was penalized, and I can't figure out what exactly caused it. A week or two ago I got 6000 profile links created. They don't appear as links in google yet but they do exist. Is it possible that these profile links caused the penalty? I didn't do much else in terms of link creation. Are 6000 profile links a big red flag to google? This site is not a commercial site and doesn't target any competitive keywords. It's about books and writers. I am a bit surprised google would even care about it.
