Developing and maintaining these bots is not without technical hurdles. The primary challenge lies in the file size limitations imposed by WhatsApp. Standard WhatsApp messages have a cap (typically around 2GB for documents, but much lower for standard media), requiring developers to implement video compression algorithms to shrink large YouTube videos into shareable sizes. This compression often results in a trade-off between video quality and file size. Additionally, YouTube frequently updates its algorithms to prevent unauthorized scraping of video data.
