No idea, but people in that scene get killed, there's a lot of connections between some reggaeton artists and local drug lords, including being funded by them and protected by them. By insulting every rapper you can lash out against, chances are high, you will anger some very dangerous people, think of like angering a cartel boss' favorite celebrity that he built up and funds.
Hector "El Father" was very much underneath the biggest king pin across all of Puerto Rico, who kept all the different barrios / caserios at peace since he was the big chief, but after the government arrested him and those closest to him, that all changed, its kind of like how in Mexico all the cartels had a "federation" they didn't mess with each other, but they eventually lost control of "peace" amongst each other, in Puerto Rico's case, after the feds took the top guys to prison, all the different barrios / caserios not only went their own way, but it was a bloodbath of people trying to be the next in charge, so its a little more dispersed.
Not every reggaeton artist is "affiliated" this way, but a number are and can be. It all went back to a moment back in the 90s / early 2000s where they arrested rappers who lived in these neighborhoods with other drug dealers, as a result some artists fled further towards these types of people since they felt like the government was associating them all the same and arresting them the same. At least this is their view.
Wild world.
Edit:
Some rappers here in the states have similar things where they pay to be protected by gangs, or they were in specific gangs, and that gives them access to protection across the country, or specific states / regions when they tour.
The Game most recently noted he's the reason Chris Browns is "in the Bloods" in his latest album, which surprised me to hear, but googling around, apparently Chris Brown claims to be a member, even though it probably just means he pays them for protection.
