"Buy/gain" blue standing with a corp or alliance?

I realize this question is probably depending on the said corporation or alliance, but I’d like to know if it’s common practise.

I’ve come to enjoy low-sec PvE a lot, but the space is often used by a particular alliance. That’s EVE, but I wonder if many alliances allow small corporations to buy blue standings with them? Is that a thing? I’d rather keep low-profile and not ask them until I know more. I’ve always been solo-playing EVE, so this is completely new to me.

Just ask them. When I saw a moon I wanted to mine, I asked the owners, so I got a moon to mine, and they got some of what I mined
