If you go to the page in question (available here: https://en.wikipedia.org/wiki/Mohammed_Zakir_Meyra) it has not one but two warnings at the top of the page about the content within. Is this not an example of Wikipedia's process working as intended?
Wikipedia runs off of community contributions. This person seems to be extremely obscure, as searching the full name 'Mohammed Zakir Meyra' I found this Wikipedia article, websites that scrape Wikipedia and post its contents, and garbage SEO-optimized websites that had nothing to do with the person. I gave up trying to find anything that wasn't SEO garbage or a Wikipedia scrape on page 5 of the search results.
At least in the English speaking world, this person seems to be a nobody and nobody seems to care enough to fix this article. Honestly, someone that knows how the process works on Wikipedia more than me should probably submit it for deletion, as this (at least in my opinion) shouldn't even meet Wikipedia's notability standards.
