Spend up, sales flat - is someone clicking my ads on purpose?

Been going on about 3 weeks now. Spend keeps creeping up, sales haven't moved
at all. Same keywords, same bids, haven't touched the creative in a month.

Two things look wrong to me. Almost all the clicks are coming from one device
type now, never used to be like that. And people hitting the site are all
bouncing after about the same amount of time which just seems off.

Might be paranoid. Can't prove anything.

Blocked what I could from inside the account - locations, IP ranges, device
targeting, no paid tool or anything. Was fine for maybe 4-5 days then it
started climbing again. So either I'm blocking the wrong stuff or they're
rotating faster than I can keep up.

Anyway. Is anyone else going through this right now or is it just me?

- did your spend go up with conversions staying flat
- anything that actually held up, or does it always come back eventually
- is support worth the time on this one, I've read mixed things

The repeated device pattern and similar bounce timing are definitely worth investigating. I’d compare the traffic by device, location, IP patterns and time of day against your conversion data before assuming it’s intentional. Have you noticed whether the unusual clicks are concentrated around specific hours?...
