Treat Linkedin as a spammer

Thadeu Lima de Souza Cascardo at

I heard recently that Linkedin was going to pay for its users because they sent unrequested messages to their contacts.

I keep receiving those, but since I am not a user, what am I going to get for my troubles?

There is an unsubscribe link, but there are two problems with that.

First, it doesn't work. Even if you use it, you will keep receiving "invites" to the same email address.

Second, there is a design problem here that implies they need to have your data. This needs to be an opt-out list, since any new person who has you on one's contact list might trigger the invite again. So, in order not to send you an invite, Linkedin would need to have your email address stored.

I tried sending a message to Linkedin using their hostmaster address, that didn't work out, no response, I keep receiving invites. Their contact options require you to be a user. I guess spamhaus would not include them.

Any suggestions on next actions?

Indeed, I've been spammed by linkedIn without being registered there...


It didn't happen very often, so I didn't take much action, other than blocking the address that sent me the mail.

I generally try to find the true email address of the person who sent me to invitation and then simulate an attempt to visti LinkedIn while GNU LibreJS is enabled and register the results of non-free JavaScript in the email message telling to the destination how LinkedIn forces people to use non-free JavaScript.

Besides, I tell them how bad is the network desing of LinkedIn, since it's centralized and so it's users are susceptible to terms of (ab)use, censorship, and also, the risk of being unable to interact with Linkedin from outside (since it's not decentralized, be it either federated or distributed, there's no way to interact fully from outside), that is, either you use LinkedIn, or you won't be able to interact "in the LinkedIn way".

Since I started doing this, the spams are gone. :D

Oh my... And there are speakers who talk good things of this centralized curriculum vitae eater. I have even seen free software supporters talking good things of this crap... Ugh..

Hypothetically they could store a hash of the mail address.
