Mark Weinstein, the founder of MeWe, recently posted this message (I added the boldface):
All social media companies and others are in a constant battle with the bots, trolls, and scammers/spammers that have way too much time on their hands as disruptive critters. Of course now that we’ve become popular, they are doing this on MeWe too. In light of our remarkable and rapid growth, we think the competition recently underhandedly funded a sexbot attack.
You may have noticed this little invasion – in a chat, a group, or a contact invitation. We’ve got it under control and are purging the little buggers. It is a good exercise for MeWe’s engineers as we’ve developed new spam/sexbot attack tools rapidly and deployed them. If you ever encounter any of these misfits, simply ignore them, or block and report the little cretins.
As the admin of the HTC group on MeWe, I had gotten three requests from “ladies” to join. Looking at the profile pics, I decided not to respond. One “lady,” a certain Diana Di, was very persistent.
When I read Mark W.'s message, I finally understood what was happening.
This is a good question to ask members: Have you ever received this kind of request?
