It depends on your situation and your intentions. If you're trying to maintain strict no contact to move on, then probably not. But if it won't affect your emotional state or your goal of no contact, it might be okay.
There could be several reasons. His stories might be boring, or perhaps they contain spoilers for something you're looking forward to experiencing on your own. Also, he might have a history of spreading harmful or unethical ideas in his stories.
It depends on your interest in him and the type of content he usually shares. If you're curious about his life or if his snaps are usually fun and engaging, then go for it.
It depends on your situation and your feelings. If it's going to cause you more emotional turmoil or break your commitment to no contact, then maybe not.
