Google Search Console Manual Penalty
If you suspect you have manual spam action against your site from the WebSpam Team its best you open a Google Search Console account (formaly known as Webmaster Tools) using your Gmail account,.
Regardless of when you open the account the manual penalty will immediately show.
This was John Mueller`s response to a Twitter tweet from Jeff Lousella.

@jefflouella
@JohnMu Yes or No. If a site has
a manual penalty & didn’t have
WMT set up & then set up WMT
a year later, would the penalty
show in WMT?
John Mueller
@JohnMu
@jefflouella Yes, the current manual
action status is shown in Webmaster
Tools regardless of when they were
applied.
