There are some very weird pages on the official wiki, and since this seems to be the only way to reach the developer of this mod, I am posting it here.

There are several pages like these, which can be reached by the "Random Page" banner at the top in the mobile site,

(You might need multiple clicks to reach a weird page)
Edit:
I have blanked a few of these, but some are made very very recently. All of these seem to be by users with only one post
Edit 2:
They can all be found on this list:

Neither wiki admin is available for 'talk' and haven't contributed since 2017. Seeing as this is the most active "place of discussion" for this, and this being a somewhat serious issue, I am posting this here. Minecraftforums for this mod hasn't had any activity for over 6 months, and it looks less like glitchy advertisers and more like random people looking for free server hosting.
This issue is kinda serious because there are ..adverts(?) for sexual disorders ..pills(?)

Thanks @Mastergalen for clearing out the junk (https://projectredwiki.com/wiki/Special:BlockList)

Unfortunately you blocked my account in the process :(
Thanks for unblocking

I think I read somewhere that the wiki was no longer maintained, which seems to be the case since all the download links are dead. I think the site administrator should close it down to prevent people from getting to it since it's out of date.
