Feud with JAY1

In November 2019, his original alias 'Dot Rotten' made a comeback to the UK rap scene with a diss track aimed towards a UK rap artist named JAY1 (real name Jason Michael). A disagreement regarding the cost of production was the cause of the feud. JAY1 refused pay £15,000 to Dot Rotten for the production costs one of JAY1's songs: 'Million Bucks' which created the feud. It was revealed that the price had gone up from £10,000 to £15,000 due to not receiving an invitation to the music video shoot of 'Million Bucks'. Jay1 disagreed to pay the fees, and Dot Rotten took to social media to expose the situation.

Feud with Sneakbo

No joke". The same day there was apparently a confrontation between the two men, with Sneakbo posting on Instagram a picture of what appears to be Dot Rotten being held by the neck; the caption read "I don't make Diss (sic) tracks [...] when you catch the lad that's been dissing you for years inna (sic) real life... he's not even worth a beating. I just had to tell him off! This is what happens when you mention my son". Dot Rotten responded the same day, cancelling an appearance at Brixton, Sneakbo's home, calling Sneakbo a "snitch" (and "Snitchbo"), and saying "I hate predicting death.. (sic) But we're gonna lose a rapper from Brixton soon."^[14]
