@SnowMan68 generally it takes from a few days to 2 weeks for the rankings and traffic drop to follow the message. I've rec'd the message for 2 sites, one of which has never done link building. Having said that Google doesn't care whether you've done any or not. 1000s of sites are getting hit with this.
Print out all your links, go through 1 by 1, look for anything Google might not like, do everything you can to get rid of the links and document it, ask for reinclusion sending Google a link to the documentation of all the work you have done. From what I have heard you may have to "rinse and repeat" the above a few times until Google decides you've served your punishment and you can be let out.
