worth noting, that blacklist filtering decompiled code looks this way (just one line; to show the naming)

    if (iNativeAd.getAdTitle() != null && m12161a(iNativeAd.getAdTitle(), str)

If to believe the naming, it is filtering advertisements.

That would be my interpretation as well - these non mangled names I guess they come from an api.
