Here is what snopes has to say about spokeo. It maybe better to try not to remove yourself. Lukily I used my junk email address. Read the info all the way at the bottom.
I almost wonder if this is something that should be reported to BBB or is it just one of many companies doing this as the link suggests Zabasearch or whatever has been doing this for some time. I attempted to remove my info too and thought it was strange the way they did not verify and then it only allows you to use one email address x number of times. Strange...so yes they probably are attempting to collect email addresses for solicitation.
Re: snopes on spokeo
I had a feeling too. I also think they may own the protection company they are advertising. It is all just a little fishy!
