As far as I’m aware, twitter has actually been a lot smaller in terms of users than you might imagine from its influence.
It has a relatively low number of active users, but the fact it’s designed to be a centralised public forum (rather than users being selective who can follow them like Facebook) means it is/was very attractive for businesses, celebrities and politicians.
They’re trying to work out what problem you’re trying to solve, so they can give you actually useful advice for your - frankly - very vague question
“What are you trying to achieve” is a perfectly reasonable question to ask about a deeply under-specified problem
Edit: here’s my theory:
This is a homework or interview question you’ve been asked, that depends on specific context that you haven’t included (because you don’t know what context is even relevant)
You don’t want to admit that’s why you’re asking, because you know that defeats the point of you being asked in the first place.
Hence, you’re being absurdly hostile to someone trying to help, because you can’t answer their question without admitting you’re trying to cheat
Lula Brazil is very different from bolsonaro Brazil
