"From the types of sites people seem to be doing this on, you aren't getting any benefit (since there will be no links to the user profile other than those you create yourself)"

While I do not support this as a legitimate link building practice, I would need to disagree with that statement.

In fact, in several genres I watch involving in health, people utilizing this tactic alone have managed to get single articles written around that topic on article repositories to upper positions.

A check on all backlinks to the article show only profile links, and these are pages that were previously on page 2-5 for the same term.
