Some people are confused about whether they *need* a VPS. This post should clarify things for you.
So there are various scenarios.
1) You only want to use a single Pinterest account
You don't needa VPS. You can use your home computer if you don't mind leaving it turned on all the time.
2) You want to use a few Pinterest accounts and are happy to leave your home computer turned on.
You still don't need a VPS - you can do it all from your home computer.
BUT... you do need a private proxy for each Pinterest account you intend to run.
This requires a little advance planning to work really safely.
If you know in advance that you will create multiple Pinterest accounts, get private proxies and use one to create a Pinterest account. Always use the same proxy in Social Multiplier to access that Pinterest account.
3) Like 2 above, but you don't want your home computer on all the time.
In this case you need to think about a VPS (or see below).
The VPS is just a computer in someone's office and it's left on all the time. You're just paying to rent it and do what you want with it.
But here's the thing - it's basically exactly the same as your home computer. It's just sitting on a desk somewhere else. That's it. So what you can do on your home computer, you can do on a VPS. You just use software to access it and control it.
So the comments about your own computer apply equally to a VPS. You can run a single Pinterest account on a VPS without any proxies.
If you choose to have multiple Pinterest accounts, you need proxies for each one (ideally from the day you start creating those accounts).
4) You want to run 20, 50,100,500,some other big number of Pinterest accounts some day.
In this case you're going to need a VPS for each block of Pinterest accounts. How big is a block?
Depends on the VPS.
A cheap and small VPS might be fine for 3 or 4 Pinterest accounts. A bigger VPS might be fine for 20 Pinterest accounts.
You'll still need a proxy as well for each Pinterest account in that case.
Some people have older laptops that they can devote to running Social Multiplier at home, all day long. If you're using proxies for your multiple Pinterest accounts, Social Multiplier will work just fine that way. Whether your internet connection is powerful enough depends on the speed you get.
If you think you might want to run multiple Pinterest accounts in the near future, it pays to create and access your accounts using proxies (one per Pinterest account remember).
If you already have an account that you use from your home computer, you can continue to do so. Just be aware that if you suddenly access it with a proxy it may be a red flag to Pinterest. You have to be consistent as much as possible in how you access the accounts.
