No engine matches - why?
in Need Help

I started getting links rather slowly. I use 22 private proxies and 60 threads. Proxies seems to work fine (bing, google testing). I also use serverifiedlists and no scrapping. Is problem in proxies, or what else could it be?

I am scraping on my own and sending GSA SER Links after passing through the GSA PI
Do I need to make any special settings to avoid this kind of error?
Or is it normal?
Or maybe that is not a good idea since "wrong engine detected" simply means that GSA PI could have sorted a link into multiple platforms, so one of the platforms could be the correct engine to USA in GSA SER
Here are some examples from log with "no engine matches" error:

Do you know, what engine is it with /bbs/ in url? I think, it's better to uncheck it in project options
UPD: Already found, it's GNUboard
