Who is this .pl domains that stealing titles, categories, tags, feeds, etc?
 

They are annoying. All my sites are their victims. I also see other sites. If you click, it will redirects to porn sites, ads, adult landing pages, and virus ads.

The worst part is, if you search for your site keyword, they are on the top!

Should I worry with these Poland guys?

How can they "steal" your feeds? The RSS feeds are made for easy syndication of your content (yes, with titles and categories/tags) by other sites. If you don't want to provide the RSS feeds to others, just disable them.

FYI: RSS = Real Simple Syndication

CyberSeo, so maybe he should disable website to prevent stealing??

i dont think he is from poland, he just buy expired pl domains, but who knows :)

just report it to google fast as possible

What for? Sounds like a bullshit to me. If you don't want to provide your RSS feeds to other sites, just stop doing it.

I know 3 .pl domains that doing this so far. This is the registrar

REGISTRAR:
nazwa.pl sp. z o.o.
ul. Cystersów 20A
31-553 Kraków
Polska/Poland

But in fairness, they are smart. They linked all the content of a site so all the info of a site are scraped in. If you search your domain name and some important keywords, this .pl domain is on the first page and even on top.

So your site dropped on ranking. My advise is, if you have time try to investigate more about you domain and your keywords, may this .pl domain owned your site.
