After uploading a video clip of mine to YouTube for public viewing, I received the following message via YouTube:
Gracehapp has sent you a message:
whats going on? great video
To:[my YouTube ID and 19 others]
wow i like ur channel im gonna sub to ya..if you want more subs i used a website
called sub4sub.com you can enter everyday im after getting 300 subs since yesterday.
keep the vids coming
If you receive a message like that (even with other domains in place of ‘sub4sub.com’), report it to YouTube as spam. To the right of the YouTube logo at the top of the message you will see:
help center | e-mail options | report spam
click on that “report spam” link.
It looks like the same spammers previously used the domain earnsubscribers.com, which was advertised using identically worded messages.
