Are these red flags?

I have a fairly new bf (not 6 months yet) but he has several social media accounts and he said he want to delete it he barely be on it. Like a lot of ppl say that but ok. Then I was talking about Snapchat and he said it’s lame but I saw a girl sent him a snap… and he claims he’s barely on ig he’s following 800 ppl and when I posts he watches it so he’s definitely active on there. He also get notifications from other apps so it’s just like why r u saying things u don’t mean I could’ve kept that to yourself. there’s a reg flag from another post that 90% of ppl voted he was seeing someone so I just want to see if this supports it or not.
