At beginning of 90s you were limited usually by 3 letters in games so just used in general my name initials combined in various names like PDO, TED were I think the most common. I think my first full nickname in mid 90s was Markoff inspired by reading John Markoff's book about Kevin Mitnick, I just liked the sound, I like in general those names ending -off before I even knew it's transcription if Russian names. I used this nickname for maybe 10-15 years until it became unbearable, because it was not anonymous at all after few years in my small home country anyone a bit familiar with internet could figure out who I was. Then I wanted to become anonymous online again since nickname made hardly any difference over my real name. Since then I just use quite random made up names and word combinations usually some clever plays on existing popular phrases, one was for instance replacing Berliner in IchbineinBerliner with word with similar meaning, the other is play on dark chocolate, white chocolate replaced with particular color combination for people in tech you won't certainly find in shop. So since first nickname I'm actually still using the second one on many sites with exception of Reddit where every few years I change nickname to start fresh.
