PBN deindexed and reindexed without any changes

Hi,

yesterday I noticed that 2 domains of my PBN were deindexed (never happend before). For 1 of the domains I created a Webmaster Tools account to see what happend
with this domain. After seconds I got the message that the domain was marked as "pure spam" by a manually check on 10/07/2015 - 7 days ago.

Today I checked the indexation status again (for no reason) and then I didn't believe my eyes: The domain is indexed again with all pages. I changed nothing - only created the
webmaster tools account. The other domain is still deindexed. I don't understand what happend here. Does anyone have an idea?

Both domains were bought in Godaddy auctions, one in November 2014, the other in January 2015.

Maybe someone has an explanation.

 

Your PBN's are gone, mate. Soon as you identified it on Webmaster Tools they know you own it.

 

Well, that would apply when I use 1 webmaster tool for all my sites or same IP, or same cookies etc... After building hundreds of sites for my pbn I learned
how to avoid footprints.

The Webmaster Tool for the site which got reindexed were created with clear browser, new IP and of course new G acc.

 

Really,
My PBN domain indexed well when I added them to GSA

 

Remember that Breaking Bad episode when a fly got into the lab and Walter had to kill the fly at all costs?

That's the case here

 

I remember with joy. So you think the best would be to just ignore the strange things happend to my pbn site? I thought it could be important for the future to find
out why it got reindexed again (reminder: after "Pure spam" mark).
