Completely agree with this categorization here. I know Derpi can be a bit hard to categorize. Lot of people want to classify it as TurboLeftNazi but in reality it has been held, however uncomfortably, to close to the status quo  always sucky, with egotistical mods stuck up in their own arrogance and world view  with little organic changes to policy in either direction. 

Manebooru certainly deserves to be separated in its own block as well. 

> Note: Bronyhub hasn´t been considered for these charts but just in case it were included at some point, presumably it would be placed in this category.
I believe the owner of it even called it quits recently if I recall right. It had so little traffic that Pathos was able to comfortably host it from home and never hurt his own traffic. I imagine what affect they would have would negligible. 

> So, I had the idea at first to make a representation of these sites as if it were a parliament. Instead of going for usual tags, I would like to introduce a more neutral concept in order to embark on this matter: intrusiveness from the staff members.
I could see some issues with the definition of intrusiveness. Say, in some ways, Twibooru polices what counts as fandom a lot more vigorously than Ponerpics and Ponybooru. Would that make the staff more intrusive? Or would it's  blatant ignoring of the copyright system make it freer and the staff less intrusive overall?

>  either nearer Manebooru or the alts. 
If you rate it by censorship. Manebooru. It is more than Derpi from my understanding of them. If you rate it by alignment that might a little more complicated but I would still lean to putting it next to Manebooru. I remember seeing SJWs smirking off to there over Derpi early on, but the owner doesn't want to deal with politics at all and (at least in the past) shutdown the attempts to start any drama. I am uncertain of overlap with the other altbooru users but I do see it mentioned in the circles I hangout with from time to time. 

> Now, what do I mean with said 20%? Here is the main problem that makes these charts certainly skewed. A controlled variable but still an error nonetheless.
Yeah, we do not know the exact amount of overlap between the sites and the fandom at large. Furbooru could easily have a higher number who are from Derpi, considering their advertising has been significant there. Or they could be showing up in google images a lot durring Furry searches and the core fandom crowd might be a tiny minority of people at this point.
