When I list an item on eBid I usually share the post via eBid to facebook, twitter and pinterest. Today when I clicked the link, Twitter wanted to verify that I wasn't a robot, well and good, I went through that, but then asked me for my mobile so that Twitter could text me a code to verify who I was.
I did not proceed, and will no longer be posting my items to Twitter.
All this is happening via the eBid link to Twitter.
Does anyone else have any reservations about giving mobile phone numbers to Twitter? Can eBid have an arrangement with Twitter to by pass this?
