Hello,
Unfortunately some hostings do that. I encountered that same problem with multiple users and it created conflicts with some plugins. You need to talk to Tech Support to solve this situation, because sometimes (previous experiences) if you delete them manually it could affect your site.

We have some sites of our clients in bluehost. But no such problems so far. may be some free plans?
Well, before doing that, contact your hosting support first. It was an automated script that put those links on your elgg site. I'm sure tech support will help you removing that.
