They do NOT really know who the reporters are, but some people are pretty good ant ACCURATELY GUESSING WHO PROBABLY reported their question or answer, because behavior patterns are VERY CONSISTENT.. My behavior is just erratic enough , both intentionally AND unintentionally, that i dirve some people who have been targeting my answers and email accounts for years even more crazy.
NO ONE REALLY KNOWS WHO reports their questions or answers, but usually their guesses ARE accurate, but NOT ALWAYS.
Yes, people often DO accuse other people on YA and often they are TOTALLY wrong.Some people acutally SAY they have reported or will report something, I've done that myself.
Account level and how old the account is tells you NOTHING, because lots of people have relatively new accounts, but they've been on YA for years. i've been on YA for more than * years, but this account was set up on September 23, 2017, I think.
