You'll need two accounts for this. Long into your non-main account and go to your main account's profile. So you have the option to follow your main acc. Do not. Open a second tab and log into your main account. Now it's easy. Go back to the first tab and click follow. (You are technically logged into your own account via the other tab, but of course, the first tab is still on your other acc.) If you don't think it'll work, check my followers. I'm one of them. .w.
