Spamtrap detection promoted in YouTube advertisements

[Randolf Richardson 張文道]

This week I saw some advertisements from sendx.io on
YouTube promoting mailing list services, some of which
emphasized that they perform "spamtrap detection" (other
ads from the same company also emphasized "Built-in
Email list Cleaning" which is just a fancy way of
writing "list washing").

I'm thinking about adding them, as I have for others who
promoted the same, to my block-and-forget lists since
they obviously want to provide services to spammers.

I'm curious, what are your points of view on companies
that promote such concepts in their advertising? What
concerns do you have about them and their apparent (as
advertized) practises?

Thanks.

Isn't it better to ask in spammer's fora?

True, but there is also the situation where people intentionally put
spamtrap addresses on mailing lists to let the company list itself to
annoy them.

I would suggest to monitor that first and if they behave
spammer-friendly, reject their junk by default.

Confirmed opt-in protects against that, unless the
spamtrap address is controlled by the saboteur who
follows the opt-in confirmation steps.

That seems reasonable. A first-time subscription opt-in
confirmation request is soemthing I'm not concerned about,
as long as it's also not filled up with advertisements.

The opt-out auto-subscribed eMail lists are unreasonable,
and I regard those as spam, and are therefore worthy of
inclusion in blacklists.

I have put their domain name on my index.html
Somehow the spams stopped that way

Oh, now that's interesting. I wonder if they consider you an ally
after their spiders re-visited the web site, or if it's just a
coincidence.

Such amateurs don't use spiders.
I guess they searched in search engines about what people say about them

When I worked at the university, someone used the opt-in mails to flood
other machines with those mails. This can also be used to hit spamtraps.

Register 50 domains and point their MX to the trap, then enter those
addresses.

High probability that you will be listed.

This is probably one of the reasons people send opt-in
confirmations from IP addresses that are different from
what the main mail servers normally send from.

Such vengeful activities may always test the limits of
the systems. :(

If they can be shown to demonstrably send spam, I will block them. If they
look a little sleazy like this I will usually give them the benefit of the
doubt until I receive a spammed message from them and then I will block them
the first time around.

A number of these large list management companies send a lot of spam and
get blocked here.
