We did some research about portal links and we have some analysis data to spread!
So there are portals with 12 links on them, but linking that much can be tricky.
So if you try to link to other portals, you will have to stop on 8: you will get message that you have too many “originating” links. This is a clue, that means that you can have some incoming too. So you go and link create some more incoming links but the max number is 12.
So maximum number of links on one portal is 12 with incoming and only 8 originating. We will research if we only create incoming links what is the limit.
