Brandon018 said "I notice a lot of emails that appear to be fake from people asking about items in the classifieds. This has happened lots before but seems to be much more lately. Is this happening to other people as well? "
Sometimes Gmail gives "warnings" (see picture). Through careful interaction at first, I have found that these are actually legitimate local people. I have no idea why Gmail marks these people as spam.
Is a "warning" like I posted what you are seeing?
