At which point twitter will probably yell at you to "verify" with a phone number or something else tied to your government name. Yes you could probably go get a prepaid SIM for cash (depending on your country, many now ban this though America doesn't) but very few people bother with it. Or they just lock your account and demand your ID which I think they now sometimes do.
You can pay $5 for a verification phone number. It's not hard.
There are so many more ways one could screw up, and you only need to screw up once. For example, does X do browser fingerprinting and did you ever use similar setup to use a more identifiable Twitter account? Are you using unique phrasings or behavioral patterns? These things can be solved to a satisfactory degree, but I don't think "it's not hard" captures it - for an average user it _is_ hard.
