I know license issues are difficult. I have tried to get contact with one font creator for last month to get that font properly licensed.

Many of free wallpaper and free music/sound websites are granting license to use the content for free to personal use only. Often that does not include right to redistribute and almost never commercial use. Last one we can ignore when we are sharing those for free, but other restrictions not.

There are also many sites which do not tell anything about license terms nor copyrights. Many of them are sharing content illegally and/or without permission or they are only linking to content on other sites. Sometimes it is very diffucult and frustrating to try to do everything by the law.

But hey, better that this community raise the flag about this than some corporate laywers closing whole site and openrepos too.
