colorlib.com é seguro?

Possible scam; certainly a source of extremely low quality bulk boilerplate templates / "themes" easier to implement from scratch. There is little reason or excuse to use templates like these in place of actually learning the smallest amount of HTML and CSS.

Colorlib is a scam company, they offered a misleading license for their templates, only a year after purchasing they claim it was just valid for one year... This was never clearly specified when buying the license, and customer support even told one customer who asked before buying, that it was in fact a lifetime license.
