This is probably because you did not sent your message as plain text.
This is explained in the Statalist FAQ

What is recieved wisdom is very much dependent on which
(sub-(sub-))discipline one belongs to. Here is a fun quote:

"Econometrics texts devote many pages to the problem of
multicollinearity in multiple regression, but they say little about
the closely analogous problem of small sample size in estimation a
univariate mean. Perhaps that imbalance is attributable to the lack of
an exotic polysyllabic name for 'small sample size'. If so, we can
remove that impediment by introducing the term micronumerosity."
