Well, I use a vpn when I bot but I don't do multiple accounts simultaneously. I haven't really been banned while using them, it's only when I forgot to run the vpn client and fucked up the OSbot settings and now I'm like 90% sure my IP is flagged lol. But be cautious though, there's a lot of threads right now about mirror mode not working properly for them (at least when I was still VIP like a day ago). If you have a Mac then forget it lol, it just doesn't work well at all. Not to defer you or anything, but this is my experience and I want to warn people before they get mad.
