If the bot(s) ever stop working the most likely cause is a change in syntax at
Wikipedia:Good articles/all or
Wikipedia:Featured articles. The bot parses these pages and expects a certain format. The functions are getlistfaa() and getlistgaa() in fambot.awk and gambot.awk respective.
If a page name is reported mismatch but otherwise looks exactly the same, check for hidden characters by deleting from the source list (eg.
Wikipedia:Featured articles) and manually re-typing - not copy-paste.
