Is using 17track sus?

Title says it all. Is it suspicious to use it to track domestic mags?

I don’t think so. I track all my packages, even non-pack packages, so they’re all centralized.

with all due respect, let me reframe your question

"is it suspicious to track my mail?"

no, they provide this functionality for a reason (so people will use it)

with any carrier, the concern is frequently checking tracking using a device that is leaking your location in the event you encounter a domestic seizure and are being watched

however, and you may already know this, U5P$ *will* set off a flag in their systems if you check packages over tr. i never figured out if it was immediate or there's a counter threshold but either way just don't do that.
