+Some plugins utilize global per-feed content hooks which either modify fetched feed XML data (i.e. fixing broken XML) or even generate it entirely, for tt-rss to process, for websites that don't actually provide RSS feeds.
-This method of handling feed data entirely bypasses rate-limiting and article duplicate checking done during normal feed update process. A badly written plugin using <code>HOOK_FETCH_FEED</code> may cause your tt-rss feed to keep updating RSS feeds indefinitely, processing articles every time, causing unnecessary CPU load on your server.
+While having this ability available for plugins is valuable there are several downsides:
-If you have full text content plugins enabled, this may cause excessive load on origin server, because your tt-rss instance is going to scrape site content for every article on every feed update.
+1. This entirely bypasses rate-limiting and article duplicate checking done during normal feed update process. A badly written plugin using <code>HOOK_FETCH_FEED</code> may cause your tt-rss feed to keep updating feeds indefinitely, processing all articles every time, causing unnecessary CPU load on your server.
-This may result in your tt-rss instance being banned by origin servers for causing excessive load and/or your VDS being suspended for bad behavior.

-We recommend not using such plugins unless you have a strong need for them. If you do use them, please don't enable them for all feeds.
+This may result in your tt-rss instance being banned by origin servers for causing excessive load and/or your VDS being suspended for suspected bad behavior.

+Additionally, tt-rss being blacklisted by feed publishers may affect other users.
