Back in probably 2007 or maybe even 2006 I remember hearing about Twitter, which was a small but growing social network at the time. Being in domains and knowing about forum handles, I thought I should check Twitter handles because it was close to a 'landrush' type situation. Sooooo many common words were available, but I only registered a handful because I thought they would somehow be able to flag it, and I didn't want to be too obvious and lose them. I probably wouldn't have because it was during an early period where they were likely just glad to see growth in accounts. I used to have @Toronto and another major city out West 'ahem'. I registered a few other three character (LLL) type names, and a few other words. Should have done more and spent more time searching for short popular words like pure, blast, flair, push, strike, beam, the kinds of words companies like to use now. Then Twitter got popular and all the good obvious words got taken up. Then in the 2010's there was a period where if you saw a username had an account but wasn't being used, you could contact Twitter through their support form and request the handle, saying it was for your business or whatever, and often they would just give it to you. I got ones like @ scary & @warfare that way (in the late 2010's my email got hacked, which is another story in itself, and they managed to steal those two Twitter handles, only to get them suspended later, which they still are). If your handle gets 'stolen' it is veeeeery hard to contact Twitter and have them do anything about it, at least it used to be. Today I still have a handful of words and LLL in handles, some I use more than others, but try to login or post at least every few months so that the accounts stay active. Each handle has to have it's own unique email which is a hassle the more you acquire, and I think you can have up to 10 handles on one phone number, and create a 2fa for each handle, the security is a lot more than it used to be but it probably helps to cut down on people losing accounts.
