o/t.......e bay-un-blocking my acct.

Hey fella's,
i just tried to watch an item and ebay blocked me from doing that? i had to click a link that allowed them to verify my phone #, ebay called within 30 seconds and gave me a pin # i had to put in, my acct. was then un-blocked and all was good. has anybody else done this?? this may explain the mass blocking of bids by ebay, not the sniping services. i did not have to change any password or user i.d.
