It's pretty obvious /v/TIL has been taken over by alts with months-old accounts that were registered on the same days.
These 'users' have never left comments and seem to be posting now to hoard easy SCP through this popular sub. Their post links are to Wikipedia (a non spam site) but we've seen before that accounts use this tactic of posting benign material at first to garner SCP before the heavy handed marketing begins.
These guys came out of the woodwork to post in TIL heavily yesterday and today.
Since TIL has no active mod no deletions and bans can take place if these users really are spammers (which I'm convinced they are).

EDIT 09/09: It's obvious that /u/AustralianPolice and /u/EnglishPolice are spammers doing the same thing.
