As opposed to manga, most manhwa/webtoon is not printed, but released online. This result in the format you see of long strips of panels in manhwa instead of a fully packed pages like manga.
You can't release blank pages in manga for obvious reasons, but in webtoon, they can be used as a storytelling tool or just improving readability in general.
You can see that some manhwa (korean, not to be mistaken for its Chinese counterpart, manhua) try to cheat weekly chapter length, not by increasing blank strip length (since having blank strip is like an industry standard, used in manhua to separate panels), but by recycling panels - by dedicating 50% of chapter to flashback to previous chapter, 30% of chapter to random panels of mobs reaction, without actual content, and 20% actual content.
And then, on the other side of the extreme, there is manhua that while it still has blank strips between panels as usual, each chapter just seems to go on and on without end - as if 2 to 3 chapters of manga worth of actual content in a single manhua chapter. TOG is a good example for this type.
Plus remember that manhwa is fully-colored while released weekly, with less regular breaks compared to manga (excluding special reasons like author's health condition, etc).
TLDR; This is just how manhwa is and has been, in terms of style. It is not a cheat or anything. Plus, if you try to read it in the official phone apps, the manhwa style is a lot better in terms of readability than a manga, and each panels seem to fit perfectly without unnecessary little bits and pieces from other panels you are not reading, affecting the panel appearing on your screen.
