Well, it's hard to do it. I think the best way is to use BlurtSQL (soon will be published for everyone I think, because it's ready :P) to check the post created using blurtlatam and other interfaces.

Most blockchain operations do not record information from which interface they were added. Only adding posts and comments does this, although it is very easy to impersonate another application (however, this continues to be a statistically small group of people - I think).

I'll try to extract this data somehow.
