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.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.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 real chaotic entries.
