It does have filters yes. Keyword filter is of course very important. I was purely using the program from scratch. There's also an ip blocklist option. The bult in spam filter is next to useless. Probably another learning filter based on LW's. But I have not explored the option yet.

BTW the person who designed the spam filter for LW joined Frostwire in it's early days but then took a several year break. Not sure where he is now. Torrents in LW variants was also his concept. He had his own version of LW that had a lot of new ideas in it. But that was 5-6 years ago. Well before LW ever added them. That was back in the days where a lot of LW's ideas came from users like him, experimenting with their own concepts & adding code to the official code & fixing bugs, etc.
