"Delete everything older than X days" doesn't really delete everything from the activity log

[maxigaz]

Using the script with Greasemonkey 3.9 and Firefox 50, this command seems to remove only a few things from the activity log.

After I let it run for a few minutes, even though both Autoscrollen and Run are checked, it just stops. If I keep refreshing the page and navigating to where it should continue, it starts to mark items again, but it only hides likes and messages about new friendships from the timeline and it completely leaves tagged photos and group posts alone.
