Conpiracy theory: someone wants to track you. It looks like a typo but switching one letter in an uncommon word can make the word a unique enough fingerprint to track an account. Of course I'm assuming you're typing on a computer that has been compromised.

Alternatively you have fat fingers and use Linux (is there a correlation?) and you hit AltGr+T. From Wikipedia about British keyboard:

  Using the AltGr key on Linux produces many other characters and symbols, e.g. ¹²³€½{[]}@łe¶ŧ←↓→øþæßðđŋħjĸł«»¢“”nµΩŁE®Ŧ¥↑ıØÞƧЪŊĦJ&Ł<>©‘’Nº×÷· (If reconfigured as a compose key, an even larger repertoire is available)

It appears your brain has been compromised and needs an antivirus scam.
