"Prokonsul Piotrus" aka just "Piotrus" is a rather controversial figure. He has been bought up in not one, but TWO arbitration cases, one of which is now in the voting phase.
I stopped trying to add any content to Wikipedia years ago. WP:Notability is, quite possibly, the worst thing to ever happen to that website, and I got sick of deletionism bullshit.

A problem to watch out for is that if you add your own research to Wikipedia (even with all the proper citations), you'll get slapped by some self-important wikipedian because it is apparently wrong and evil to have the person directly responsible for the research itself to be included in the creation of encyclopedia content about said research.

A while back, about a year ago, I spent my time correcting wikipedia - the corrections I made were accurate, meaningful, and relevant to the topic. However, my additions and changes were mostly removed within two hours of my posting. Perhaps those who run wikipedia do not like my educated improvements. One incident that sticks was when a friend and I added a section dedicated to the problems with genetic algorithms; by the next day it was removed. I had sources, a good and well written arguement, and it was fairly long and not biased (at least my professor thought so).
