The result was redirect to Idol (Polish TV series)#Season 4 . Salvio Let's talk about it! 16:56, 26 June 2014 (UTC)
As written, clearly fails Wikipedia:Notability (biographies). Second AfD in 2012 was closed as after two relists nobody cared to vote. The article has already been deleted years ago from pl wiki, which has a much less strict notability criteria ( [1], [2]), and that's a big red flag: if something is not notable for pl wiki, it is certainly not notable for us. Nobody has bothered to recreate his bio, even through around 2011 he briefly appeared on Polish Big Brother ( [3]). Outside one of two short news pieces from that time, I am not seeing any reliable sources about him or his career. I don't think he was notable back then, he isn't now, and the current substub is hardly making a case for itself.

Based on this cursory Google search, there is likely to be even more coverage about the subject.
This 18 September 2011 article WebCite ( Google Translate) from Onet.pl titled "Piotr Lato wystartował w "The Voice of Poland"".
This 17 June 2011 WebCite ( Google Translate) article also from Onet.pl titled "Piotr Lato - "Nie przypuszczałem, że mogliby mnie wybrać do Big Brothera!""
This 4 August 2010 WebCite ( Google Translate) article from plotek.pl (which is owned by Agora SA) titled "Pamiętacie Piotra Lato z Big Brothera?"
As Dennis Brown ( talk · contribs) noted at Wikipedia:Articles for deletion/Piotr Lato in November 2008 regarding WP:ONEEVENT:
The sources demonstrate that the subject passes Wikipedia:Notability#General notability guideline, which requires "significant coverage in reliable sources that are independent of the subject". Cunard ( talk) 06:51, 20 June 2014 (UTC)Weakest of keeps only because he placed 5th in Idol and was also on Big Brother, which clears wp:oneevent, and approaches multiple instances of minor celebrity. Likely, this could be sourced better, but that is a tag issue. This is admittedly marginal, but the threshold appears to be passed. Or he is at least sitting directly on top of it. Maybe the notability is more obvious to those in Poland or of Polish descent.
I understand that all editors other than myself are currently supporting deletion.
So an alternative to deletion would be to redirect Piotr Lato to Idol (Polish TV series)#Season 4 (with the history preserved under the redirect) because it is a valid search term. I would support preserving the article's history under the redirect because its three sources would be useful in sourcing and expanding the article if there is future coverage to more firmly establish notability.
