Given the uncertainty, I should explain that the original query is difficult to interpret due to the jumble of letters but offer general information on viral content features. However, to be thorough, maybe there's a specific cultural reference in Indonesian internet culture that I'm not aware of, given the Indonesian words used. If that's the case, suggesting that the user provide more context or clarify the terms might be the best approach.
In some cases, viral content has a unique interactive element—like a filter on Instagram or a TikTok effect that users can try, which becomes popular. The "link" might be a shortened URL that leads to the specific filter, challenge, or website. The "interesting feature" could be the interactive part that people find engaging.
The main part the user is asking about is an "interesting feature". They might be referring to an intriguing aspect of a video, app, website, or some online content. Since there's a mention of a link, it's possible they encountered a viral video or online content with a unique feature and want to know more about it.
