User:InternetArchiveBot (sometimes referred to as IA Bot) is a bot that adds archive links of URLs from Internet Archive to Wikipedia articles. In the past, after adding an archive link to an article, it would then add a post to the talk page describing the changes it made and requesting that human users review its edit to ensure its quality (see this example). InternetArchiveBot's talk page post functionality was discontinued in February 2018. An RfC in July 2018 found consensus that "the wording of the post is modified to give users permission to delete posts if they want to. Since talk page posts normally can't be deleted by other users, it would remove that restriction.
" This created an exception to the WP:ARCHIVENOTDELETE guideline, which states that "[a]part from the exception described in WP:OWNTALK, discussions should be archived, not blanked.
" Edits deleting InternetArchiveBot's posts do not violate WP:ARCHIVENOTDELETE, and they are legitimate edits that should not be reverted.
