Is it wise to try to remove myself from predator mailinglists?
The problem is that unsubscribing to the e-mail list requires you to follow a link send to you in e-mail. As general rule this is already something that you should be hesitant to do, even with e-mails from reliable sources. 

A predatory journal is not a reliable source of course. Even if the journal is not actively trying anything dubious with the link, a predatory journal is bound to be a small scale operation, meaning that they are more at risk of having their domain compromised in some way.

If you do decide to follow the link, please take standard precautions like copy-and-pasting the link rather than following it directly, and checking that the link actually leads to a domain controlled by the journal.
