Can I legally fetch tweets without twitter API?
<p>I am doing an RSS notifier, but I would like to add Twitter and Facebook feeds in it.
<br>
as both social networks shut down their RSS services, I am fetching the content
<br>
directly from the HTML public pages, parsing the content I want.
<br><br>
Question is: Is what I am doing legal?
<br>
 Can I be sued for "stealing" information from their website?
<br><br>
PS: I know I could use Facebook or Twitter's API, but I don't want to log-in to their services.</p>

<p><a href="https://twitter.com/tos?lang=en" rel="nofollow noreferrer">Twitter's terms</a> says the following:</p>
<blockquote>
<p>Except as permitted through the Twitter Services, these Terms, or the
terms provided on dev.twitter.com, you have to use the Twitter API if
you want to reproduce, modify, create derivative works, distribute,
sell, transfer, publicly display, publicly perform, transmit, or
otherwise use the Twitter Services or Content on the Twitter Services.</p>
<p>[...]</p>
<p>You may not do any of the following while accessing or using the
Services: (i) access, tamper with, or use non-public areas of the
Services, Twitter’s computer systems, or the technical delivery
systems of Twitter’s providers; (ii) probe, scan, or test the
vulnerability of any system or network or breach or circumvent any
security or authentication measures; (iii) access or search or attempt
to access or search the Services by any means (automated or otherwise)
other than through our currently available, published interfaces that
are provided by Twitter (and only pursuant to the applicable terms and
conditions), unless you have been specifically allowed to do so in a
separate agreement with Twitter (NOTE: crawling the Services is
permissible if done in accordance with the provisions of the
robots.txt file, however, <strong>scraping the Services without the prior
consent of Twitter is expressly prohibited)</strong>; (iv) forge any TCP/IP
packet header or any part of the header information in any email or
posting, or in any way use the Services to send altered, deceptive or
false source-identifying information; or (v) interfere with, or
disrupt, (or attempt to do so), the access of any user, host or
network, including, without limitation, sending a virus, overloading,
flooding, spamming, mail-bombing the Services, or by scripting the
creation of Content in such a manner as to interfere with or create an
undue burden on the Services.</p>

<p><a href="https://www.facebook.com/apps/site_scraping_tos_terms.php" rel="nofollow noreferrer">facebook is a bit harsher:</a></p>
<blockquote>
<ol start="2">
<li>You will not engage in Automated Data Collection without Facebook's express written permission.</li>
</ol>
</blockquote>
<p>So just go and use the APIs meant for the explicit purpose of automatic data collection.</p>
