Of course it can be negative, anything’s possible with social media. For me, so long as he isn’t addicted to it, it’s alright. As for constantly liking someone else’s photos, it depends on the intentions and if you know that person (if they’re close). If they’re a personality, a star, an unknown or something like that, it doesn’t matter. You can like something for it’s sheer beauty, I do that myself. But if you know that person and you’re constantly liking what you’re seeing, that’s disrespect, and who exactly is holding him hostage? Not me. A smart person will like what they’re seeing without ‘liking it’.
I use Insta and snap.
