Semi-OT: Strange behaviour of the letter "L"

[Strategia_In_Ultima]

What I'm talking about:

I was browsing older posts on one of the threads, and came along one of my old posts. It said "bLaster" there TWICE while I am CERTAIN I did NOT capitalize the "L" myself. I checked another thread... yup. I spotted it again in some posts, all NOT mine. And ONLY the SECOND letter of a word, never another one. Always the SECOND. I figured something was wrong. At least three people capitalizing their "L"s as the second letter? That's impossible. Again, I am absolutely CERTAIN I wrote "blaster" and NOT "bLaster". DEFINITELY not twice. And others as well? I thought something might be wrong with the server or something. That;s why I posted this.
