I have received two suspicious responses to my post in the BST saying I wanted to buy a Cracker Jack Gavvy Cravath card.
One was from an email (no PM) from
willamhouck@gmail.com and the other was a PM from member "hendrickson_zz" (who has zero posts) asking that I email
karinahendrickson@gmail.com
When you google either
willamhouck@gmail.com or
karinahendrickson@gmail.com both appear on a website called "Stop Forum Spam" as having Nigerian IP addresses:
https://www.stopforumspam.com/country/ng
https://www.stopforumspam.com/country/NG/4
Anyway, just a reminder to google suspicious email addresses.
