It's a form filler, nothing more. Most sponsors get that and don't consider robo "automatic entry" - they are referring to "bots" or programs that enter FOR you.
However, some do say it is a macro, and therefore not allowed. Every person has to make the decision for themselves on whether or not to use Robo.
If you are referring to Auto-Fill, same principle - it's highly unlikely the sponsors check or care as long as we come to their site/form ourselves and enter.
