A little trick to spam the spammers (2021)
I run marketing email databases. This is cute, but it doesn't actually do anything in most systems - either the employees all already get the marketing emails or there is a system-wide rule to suppress against the email domain.<p>If you actually want to (potentially) break something, try submitting some obscure characters or malformed html into some fields. Blank spaces in emails can particularly be a nuisance.<p>And if you want some real fun, some systems only enforce validation rules via client-side javascript. If you block them, you might be able to submit some <i>real</i> chaotic entries.
