All metal, and aluminum especially, has this nasty habit of propogating cracks over time until the structure breaks. The most vulnerable part of the bike frame is at the welds. The crack will not stop at the welds, it will, rather, reroute itself to follow the weld line. Eventually, the weld will fail.
Keep away from a cracked aluminum frame. If the frame has a crack, IT WILL FAIL IN TIME. This is not opinion; this is fact.
PS. I just looked at the picture. It is junk. The crack will simply propogate around the weld until the frame fails.
