You’ve received a private message from Dell Community Forum

I don't know where else to post this.

I keep getting these private messages here with subject "You’ve received a private message from Dell Community Forum", and they say: 

"Hello, I’m your Dell virtual assistant. In case you have a question about your Dell system or need technical assistance, may I have the Service Tag or Express Service Code or order number, please? I’ll validate your system warranty and get back to you with the available options."

However, the message doesn't reference why it's messaging me, or any forum links, or anything other than a link on how to check my service tag... I already know how to check it, and I didn't find any answer with it, which is why I posted to the forum.

So, I'm getting essentially spam private messages from Dell or something (a bot? a support rep?), saying "just in case you have a question! give me your service tag!" What? Why? I already posted my question in the forum. This is silly.

If whoever sent this wanted me to contact them instead of posting to the forum, why wouldn't there be a button to do that front-and-center when I get to the forum? And on every page to make a new post? This is redundant and inefficient, ambiguous, and spammy.

I don't know what to do with these or how to stop them. I've replied to them before, asking what they're referring to exactly, and I get no reply. So it seems pointless on top of it all.
