Problem Discription

I was trying to scrape some tweet posts for personal use and I ran into this strange thing.
I got 7 different cases from my sitemap every single time.
And interestingly,after I tried zooming out the webpage I got 27 results.
Would any one help me out and explain it please? Highly appreciated.

@Webb_Wen Hi, it appears that the website is pixel-based and after scrolling down the page the previously discovered results are replaced by the newly discovered results(discovered result amount will not surpass a certain limit). Unfortunately, you can consider it as an 'anti-scraping' mechanism.

@ViestursWS thank you for your kind reply and sorry for the fact. I really need the hashtags for my social network analysis. It seems that I have to repeat the copy-and-paste moves again and again.
