Help💡 How to buy multiple GMODs?

I have a separate Steam account that I want to use for buying multiple gmods on. Seeing as how cheap GMOD is right now ($2.50) I want to take advantage and buy as many as I can. How do I go about doing this? Do I have to make multiple Steam accounts and buy it on each of those? Or can I just buy it as a gift and eventually send it to myself as needed?

If you want seperate gmods for evading server bans, just use the family sharing option. The problem is if one get's VAC banned, they all do.
But if you really insist on buying seperate ones, I'd just put all the money on one account, create seperate steam accounts, then gift gmod to them.
