Hey @initforthemoney!
When using steemfollower.com, you only need to enter your posting private key at steemconnect.com
steemconnect.com created by busy.org. and you will only enter your posting key there.
You can check source code here: https://github.com/busyorg/steemconnect/
After you login, steemconnect will warn you about allowing vote and follow access which will work with your posting key.
Remember, steemfollower.com is not a bot, users manually upvote each other.
Thanks! I've joined.
Welcome aboard @initforthemoney, hope it works out great for you as well and if any questions come up, feel free to ask! :)
