Sadly, most of the places you mentioned are tourist areas, some to the Disneyland-degree. Can't tell if it got worse the last 3 years since you were there but overall the last 10 years where terrible for parts of the city.
It's not tourism per se, but the kind of tourists the city marketing attracted. Easyjetset, cheap hostels, cheap beer, the City and people 24/7 as set for the party, not limits, no rules, smashing bottles, pissing in doorways etc..that for example describes the Boxhagener Platz and it's surrounding like Warscheuer Strasse, Simon-Dach-Strasse etc. quite exactly.
Having been work&leisurewise to most of Europes bigger Cities & Capitals and knowing people there, I can tell you that the behaviours shown here lead to an arrest in Madrid, London, Rome etc..but not in Berlin. For multiple reasons. It has become a failed city, not to a degree New York was in th 80's but enough too be sad about it.
And to close this. I don't think you belong to this kind ot tourists but as always: you only get the full impression when you live in a place.
