Section 79 Liability of Intermediaries

Main problem hai, I'm stuck between sections 79 aur 80 of IT Act. Sabse pehle, intermediaries kya hote hain? Google ke paas ek article padha, jisme likha tha ki intermediaries waale platform, jaise ki social media websites, blogging platforms, aur online marketplaces hote hain. Agar yeh sahi hai, toh section 79 ke under kya hai? Liability of intermediaries? Mujhe lagta hai kya yeh keh raha hai ki intermediaries ko liability mein se free chhod denge, magar main confuse hoon. Kyun? Kya mujhe kuchh reference chahiye? Abhi tak, koi explanation nahi padhi ya bhai?
