One of my favorite YouTube channels, Linus Tech Tips, does this all the time, but I have seen many others doing this as well, and I personally find it rather obnoxious. I understand that it's more effective at getting them views, which they rely on to stay in business... but I see it as just another form of clickbait, and so when I submit LTT videos I tend to remove that capitalization.

However, are there any cases where capitalization for emphasis is appropriate in a headline/title? And if not, should titles be edited to remove them?

p.s. Acronyms and Initialisms are obviously different, so let's ignore those and put them in the "clearly acceptable" category.
