I don't see how you could be hurt in your rankings by someone unless they actually hacked your site.
The Consensus is that links either help or don't help. They can't hurt.
If you could crappy link someone out of the serps it would be like the Wild West on the web.
What do you mean by a spam message? Some one spamed a forum with a link to your site? It may have been done when your domain belonged to another.
