why google cancel index

before
google index my website pages
but why just few dats
google cancel index my pages
how can I solve it

Soon they will probably deindex your whole spammy website

You can't solve it unfortunately.

You are doing a spam website and you know it, Google also knows it in 2025, if building a spam site is that easy....

I think he is not unaware of what he is doing (spamming/autoblog/etc). Some smart people are/were trying to fool google. And it happens all the time. And most interesting thing here is a lot of people become successful by this types of blackhat method.

Now come to the point,

OP you need to find a solution to index more than de index. I know you don't want to play this game for long. Its an hit and run type projects. So, if you don't find a solution then build a new site. this is how things work here.
