Since the administrator @xper apparently does not feel it necessary to officially thank his members for their active participation in providing data that led to a precise theory, on the basis of which it was possible to prove the infection of the MSFN server, I shall do so here. @EliraFriesnan, @roytam1, @NotHereToPlayGames, @Ben Markson, @modnar, @deomsh and @nicolaasjan. Thank you for your confirmations with search engine results you generated from all over the world! That was a real community effort at its very best. And since my ‘cloaking’ theory https://msfn.org/board/topic/187801-msfn-and-its-lack-of-search-results-in-google-bing-and-all-search-engines-depending-on-them/page/5/#findComment-1287780, which, although based on many facts, remains a theory until it has been subjected to rigorous, unequivocal and, above all, empirical verification, I would like to once again express my sincere thanks to @nicolaasjan for his clever experiment and for highlighting the malware infestation in this post: https://msfn.org/board/topic/187801-msfn-and-its-lack-of-search-results-in-google-bing-and-all-search-engines-depending-on-them/page/5/#findComment-1287787. This made the culprit clearly visible and made it impossible to continue ignoring or denying an infection of the MSFN server. In mathematics, this signifies the end of a proof, i.e. q.e.d. And that is the most important thing for me. Cleaning it up was then just a formality and, really, a piece of cake for someone with experience, if you already know exactly what you’re looking for and have been given all the necessary information. Unfortunately, it will now take many weeks for MSFN to recover in the Google index. Not to mention the disastrous drop in the rankings of all MSFN threads.
