TreeIsLife, as Tupka217 said, Feeds is separate from MediaWiki. It is MediaWiki that keeps a log of everything so it therefore does not keep a log of Feeds. It is possible that Feeds has its own log. However, if it does, Fandom has yet to make it available to admins/mods.
Spakster, I would suggest you submit this as feedback to Fandom using this form. I believe this issue has already been mentioned to them but it never hurts to give them a reminder.
