I opened the website today and did some browsing. It's a usable tool with the web user interface. I had heard that snac had added a Mastodon Client API implementation, that this meant it is possible to use any Mastodon-compatible client with snac. But that's not true.
I haven't noticed this with the web interface yet. Have you looked at the context of those posts? Maybe they're part of a thread someone you follow has interacted with?
