A new kind of SPAM...
This is the second time I see this. Someone answers a question, references my username saying something like this:
"Thanks for sharing your advice @Minho. I also faced this problem. Visit here"
See this answer and this answer.
When you click on the link, it takes you to some "Vidmate App Download" page. I tagged one for moderation yesterday but it looks innocuous so it hasn't gotten the votes yet.
Can we check these folks out and delete the offending messages?
Is this a good question?
