Is it ok if I share “exclusive” news on my blog?

Hi,

I am looking to start a new blog in a niche. In my niche, information is scattered across multiple sources.

I am a member of many closed communities and VIP on some important forums.

Would it be ok, if I share the information that I collect from these sources on my blog after giving due credits or can it result in be getting banned from those communities?

As the information is scattered, a small blog might help people looking to read in my niche.

I am told that a lot of good bloggers frequent HN, would really appreciate their take on this.

TIA
