I hate to say this but I think your domain name just went down the dumpers.

The problem, may be that y-coach.com was picked out the blue by a spammer, not that they specifically targeted your name. However, now that you know the problem, you have to deal with it.

I am sure someone can give you the link to abuse something something where blacklists get created and see where you stand with them.

In the mean time I would be registering a new domain, and if things go from bad to worse get ready to move.
