Mail ballot fraud incident from 2016? - One of countle$s

Maybe I hear grass growing but I find it for eventual comparism studies noteworthy to mention an incident (one of many others) that happened in Vienna, Austria after the shocking presidential election fraud disclosure in spring 2016 which led to the election annulation and a month before the proposed new election. https://www.krone.at/528782 In exactly that printing company where according to initial news reports faulty mailing ballot envelopes were checked in the late hours of Sept. 8th 2020 at the official mail ballot printing company "kbprint.com" only few hours later in the night to the 9th police rushed to the site as there was an apparently burglary attempt. The rumour that it was a political attempt related to the ongoing mail ballot frauds as there were no valuables in the building was dismissed by all other medias that were AP/Reuters related as coincidential and not political related.

I am sure you are aware about massive mail ballot frauds in my opinion most likely in other European countriesby professional teams (anyway definitely in Austria since more than 10 years) so I don't get into
