Um to the person that said that they would be limited to how many leve-links you could have and essentially reduce you SP gains...

You are CLEARLY not aware that the cap on level links is three. 1 person starts the leve and 3 others link. That is the cap, there are NO further bonus to SP that can be made besides using Aspect.

No you cannot argue with me on this. It has been tested - it is fact.
