Work at home forum that I used for years and was one of the top members there.....Just went offline and got deleted. I used them in the past and had slow but consistent traffic from my signature there. Gone overnight.
Solo ad vendor that I used multiple times 3 years ago to get leads and SALES.........went out of business.
Youtube video that I had and got 5-10-20 people clicking on my link DAILY, got deleted by YouTube for some unknown reason ( This was also about 2-3 years ago).
You get the picture, right?
That's why as a marketer, you always want to have multiple streams of internet traffic coming to your website or affiliate link.
When you have a few places getting you traffic, if one goes out of business you still have others working for you and getting you business.
So never rely one one traffic source. Have a few of them running for you.
