If you were to build a malicious bot, sure. If you were to build a bot to tweet about the weather in Sheffield, you might as well use the API.
I don't think twitter is that place and it hasn't been for a while if it ever was.
I just watched this video again...
To me, the draw of twitter was you could text messages (SMS) to 40404 or get texts from 40404 from people I choose to follow. I had unlimited minutes and unlimited texts but I didn't have an app phone back in 2008 when I signed up for Twitter. The world has changed since then...
I'd say if you were to build a bot to tweet about the weather in Sheffield, you are probably better off setting up your own server to write blog posts or something like that? Maybe look into microdata or RSS or something too?
This is a Twitter account that started relatively recently - I like it. https://twitter.com/_restaurant_bot
This sort of bot has had a good place on Twitter for at least a decade, going back to @everyword.
Discord does something similar, although I feel they've gone way too far with policing it.
I think the only problem would be if this API was used by non-bots (perhaps some relays) and the tag loses its meaning.
What they don't realise is that the comment they are reading right now could well have been written by a bot.
