Hi there!
At pt.wikipedia, InternetArchiveBot is adding the parameters "|arquivodata=" and "|arquivourl=" when the parameter "|wayb=" is already present, which makes them redundant. Basically, wayb receives the Internet Archive ID, and the template/module interprets it as an URL and also fills the date from it. This was previously discussed at InternetArchiveBot, Again the InternetArchiveBot and has now been reported again at InternetArchiveBot bot editions are leaving reference errors. Some examples can be found at diffs 52781713, 52783128 53620028, 55151538.
Thanks!
