Snoh Aalegra On Sade: “Respect the Legend”

Someone wrote on Twitter, Snoh Aalegra is our Sade.
Snoh hopped on Twitter and then again hopped in the comments of The ShadeRoom.
She wrote, there is only one Queen Sade Adu. There will never be another one. This comparison is so unnecessary. Respect the legend.
It appears her gracious comment garnered her more fans as people commented that prior to the post they had not heard of her but based on her respectful response they were going to seek out her music.
Do you think the person who initiated the tweet was serious or trolling?
