Somehow I have zero ads on instagram. I don't know how that happened, but I suspect it has to do with a period of time on facebook where I was just marking every ad as not relevant to me. Everytime I visited, I'd let their system know that any type of ad doesn't suit me.

So maybe that tricked the system? My only other theory would be that they somehow know I wouldn't use the service at all if it had ads. I'm a fickle user who happens to produce some quality, original artwork for their service.
