I had a similar thing happen on my personal site, also due to phpBB2. The bad guys used an exploit in phpBB2 to upload a bunch of images of ads for cheap drugs and male enhancement products, and then they spammed links to those images to websites and in email.<p>I have no idea if Google noticed or cared, because I had nothing on my site that I expected people to find via search. I did have one page, some analysis I wrote on how to beat a particular puzzle, that was #1 on searches for how to beat that puzzle on both Google and Bing, and it stayed #1 [1].<p>[1] It's pretty funny. The page is just a simple page of mostly text, with some tables. No attempt has been made to optimize for search. There are very few incoming links, and one outgoing link (to a domain that once had an online version of the puzzle in question, but whose registration lapsed and is now owned by a noodle soup chain). I posted maybe one or two links to the page in comments I made on discussions of that puzzle a dozen years ago, and have done no other promotion of it. Yet for over a decade, it has been #1 on Google and Bing for searches on how to beat that puzzle. I have no idea why. (I have not named the puzzle or linked to the page here because I do not want to do anything that might disturb the situation. I'm curious to see how long it stays #1 without any promotion).
