I have noticed a lot of people posting a reply to a topic and inserting 1pt text after their main reply. The only way that I know of to read this text is to copy paste it into a text editing program and increase its size there. This slows down the speed that I can read the post significantly and it is getting on my nerves.

I know that I don't have to read it, but I do because I don't want to miss out on what they say (By reading the small text in a post I learned somebody was working on a campaign that might have interfered with Vasudan Imperium, for example).
What I would like to know is why make it this small?
Subscript works just fine and can be read easily. Why post something and give people a hard time? Why not say what you wanna say or just not say it at all? In the middle of a conversation would you suddenly start to whisper so that people can not hear what you said?
Who else is fed up with this? Am I the only one who thinks this is very childish?
