Same here on Android, using Chrome.
It doesn't seem to happen on some pages.
For instance, it doesn't happen on desuarchive.org/r9k
or when looking through /r9k/ threads, but if you browse desuarchive.org/
a or when looking through /a/ threads you get redirecting ads. Same with /an/. I only just noticed this, so maybe this is why you couldn't reproduce.
