He wrote this about himself:

Jovan Mandić, General secretary of the Montenegrin branch of the League of Communist Youth of Yugoslavia (SKOJ), founder of the Civic movement for Solidarity with Palestine (Montenegro)

Achievements so far include organizing mass protests in support of Palestine in Montenegro along with few of my comrades, the rallies were attended by a significant amount of Montenegrin population (going from 5% to 70% of the population of the cities attending). This has resulted into forcing Montenegro to vote in favor of Palestine in the UN as well as putting forward a resolution in the Montenegrin parliament that condemns Israel and ceases cooperation with it alongside other stuff (hasn’t yet been voted in). The movement also does frequent cultural stuff like making murals, cultural events etc. We also worked closely with BDS to stop weapon shipments to Israel for which i have been persecuted by the state.

Alongside this i am the founder of the Montenegrin branch of SKOJ (League of Communist Youth of Yugoslavia) which has been an emerging force in the country recognized by the worldwide communist movement, closely working with it as well as with other progressive forces.

Social media that i use the most is my Instagram account @_ mandicjovan _ but you can find me on Twitter as well by @comrade_manda. The official profiles of the communist league on Instagram are @skoj_official_1919 and @skoj_cg and the official Instagram page of the pro-palestinian movement is @solidarnost_palestina_cg

TLDR: This guy went from shitposting on Instagram to praxis lol.
