I was also not able to either Login or Open tinycorelinux.net from my any of the browsers. The error message - "your IP addrs is blocked due to spam protection...or something like that.." and asking for entering some Key shown on the error page.
I thought it was some problem from namesrver side blocking. But was able to view forum messages , thru Google searches. Wiered, but then after some months, every-thing was fine. Still wondering, what was the problem ?
