I was offered once, through spam off my website’s contact form which is
basically the same as the hyperkitty web interface, to purchase submissions
to contact forms to promote my business for US $0.01 each. Per that:
If it wastes someone's time (our mods/our members), then it’s not worth it as
it basically costs the spammers nothing to spam us.
The idea of a web interface is good, but, it’s always going to get spammers.
I put a 9 character image CAPTCHA on my contact form, which drops my contact
form spam from 5-200[1] per day to 5-10 per year. It does piss real people
off and I know I lose business because of it.
If the hyperkitty doesn’t have something like a draconian CAPTCHA, then my
suggestion is to turn it off. We are a mailing list, not a web forum.
My 2 cents,
Michael
[1] A high of 200 in one day is probably exceeding low, I know at one point I
had to just bulk delete everything received during a long weekend as it was
multi-thousands of contact form messages. Lesson of that story, math CAPTCHA
is useless.
