Not spammy, it is enough it was used before. Google for "domain history checker".

Did you check wasn't the domain used before?

You added too much pages daily and got hit. I think G added the same spam filtering for adult sites as for general. Imagine - 1000 articles per day on general site is impossible - it is a real spam. 1000 videos on adult tube per day - it is nothing - but now it is spam.

You got this penalty: https://www.blackhatworld.com/seo/anyone-site-only-4-results-indexed-penalty-now.1318746/ https://www.blackhatworld.com/seo/what-is-4-results-index-penalty.1395296/

A lot of backlinks quickly will kill your site.

So rankings dropped on April 20th on the old site stable ranking for years without doing anything. Did anyone experience something similar on April 20th?

Someone else too rankings drop on April 20th?

I would say competitors with weak sites are up about 1 page (from page 2 to page 1, or from 3 to 2).

It happened recently? I have the same, seems update is on the run.

It is most likely to be penalized. There is the chance to rebuild old content and rank.

This should work.

Algo penalty, domain is dead. How much pages are in index by site:domain.com ? How much pages you added daily ? Bought some backlinks ? Fresh domain or used ?

They should I think. As there are tons of sites running on the same themes, but original content.
