[Autogenerated] So considering what we've covered so far,
let's look at some general advice when crawling and scraping.
The first thing to keep.
Always in mind is to be extra cautious with web scraping.
But in particular if you're going to scrape off data from a site
that already provides an API Use the API instead and don't scrape
regarding the site's terms of service.
Make sure you read, understand and respect them.
Before you start writing a script that can scrape off any data from that site.
Websites usually have a robots dot txt file at the root of their main folder.
This file is intended for crawlers and scripts to know
what content they can process an index,
make sure your script respects and adheres to those guidelines.
Use a reasonable crawl rate.
So don't overload the site with requests.
If it's not there, then use a conservative crawl right?
Such as one request per every 10 or 15 seconds ask for written
permission to the site owner before doing anything else.
This is really important.
Also make sure you identify your web crawler or scraping script,
create a page that explains what you're doing and why a link
back to the page in your user agent string.
So if they detect you, they can understand what you're doing.
The main goal of scraping is to get data from the site.
Therefore it is really an absolute must that you do not publish any scrape
data without written permission from the owner of the site.
So the person or entity that holds the copyright.
Don't base or build your whole business around data
scraping the sites that you scrape could ultimately force
you to shut down your business.
Furthermore,
be extra cautious on any advice found on the web about crawling and scraping.
Always remember that if you're scraping someone else's website and
if you don't take the necessary precautions,
you might be putting yourself in a vulnerable position.
The main point to think about what scraping is.
Is this something that might upset someone?
You need to ask yourself?
How do you want to be perceived or seen?
Do you want to go undercover and be willing to take the financial
risk if something were to go wrong or do you want to be perceived
as a legitimate user or institution and respect the rules asking
for the necessary permissions.
There's a lot of gray areas around scraping.
Ultimately it comes down to which path you want to follow regarding on how
to identify your script with a valid user agent string.
