There's no reliable way to tell where you're logging in from.
Huh, I didn't know that California was in lockdown. I had an impression that the USA was still trying to just tough it all out.
The US States all have their own policies (remember what was happening in NYS/NYC in March/April). In terms of CA, you know as much as I do but it's pretty clear to me that the stay at home order is still in place although the counties appear to have some leeway on orders.
I’ve assumed that these are being shown because the old advertisers have run out of money or gone bust, that firms have reduced their advertising budget, or, that no one wants to advertise in the p2p category anymore.
