Watching my station with satnogs-monitor I see I’m being constantly scheduled to observe a bunch of sats. There are always 6 listed under “future jobs”. And they seem to be ones that do not appear to be amateur. Like OBJECT XT, OTP-2, LUNA-1, CTC-1C at the moment.
I don’t have an issue with that, it’s what sagnogs is all about. But how do I find out who is scheduling me?

That’s Fredy scheduling the sats 
I heard a rumor that Fredy will buy a Starbucks if your station gets scheduled 100+ times.
COMPLETELY a rumor, but maybe worth checking into….
Is it only a rumor, who knows? 
You can either use the link that @pe2bz shared and check the observer column, and also in each individual observation you can find it in the details again next to the observer tag.
I’m scheduling other stations usually on newly deployed satellites, which helps to check their status and if received to generate orbital data(TLE) for them until they are identified. Also scheduling satellites near their re-entry to track them better. Finally sometimes I’m scheduling when there are satellite events, like SSTV events.
