Your observation is interesting in that Yellow Polyps are actually a species of Colonial Anemone.
Mojano are easy to physically remove. Use a wooden dowel or just your fingernail. Don't attempt the same thing with Aiptasia, but it can be done safely with Mojano.
They are no more dangerous that your Yellow Polyps, the main reason they are considered a pest is that they can multiply rapidly.
So do you just squish them? I have a couple in my tank. I pulled the rock out of my tank and squirted it with lemon juice and let it set for a minute and it is still going strong.
