The term is to "scrape", "scraping a website". See that singular p?

Another good example to illustrate is the word "illustrate". You would say "illustrating", not "illustratting", as the magic e is replaced with "ing". A closer example to "scrape" would be the word "gape", you would say "a gaping hole", not a "gapping"

I hope this helps! English is a weird language. To "scrape" means to collect, while to "scrap" means to discard.
