No, that theory never had any substance, & was thoroughly discredited by the finale.

I imagine that the Fire Nation citizens held captive by Hama, the Southern Raiders who had their Captain bloodbent by Katara, & Hama herself all began telling stories about it. This would have inspired other Waterbenders to begin experimenting themselves, forcing Katara to take action & make it illegal. And once she made it illegal, that would have pretty much confirmed it existed.
