Am I going to get limited?

Hello there guys,

I have just got 4 negative feedback all of a sudden -- I ran out of stock and had to cancel transactions :( I also have item as described and communication DSRs 1-2 both crept over 1% (1.02%) . I can't believe it! People are so unreasonable -- they just leave negative feedback before even contacting me to resolve it, and they fill out DSRs even though I always offer to do my best to satisfy them.

Will I get limited?

My account is very old, made in 2001. What do I do if it is limited? (Most likely a selling %age limit right?)

Thanks!
