It is tough to prove if someone is posting from their home computer and then from their phone.

It is easy enough to spot and I have seen one person post the same picture on two different acounts on another forum. At the time I passed it off with their explanation that they really liked the picture that another had, which in itself was creepy.

If you think someone is posting on several diffent accounts, then just ignore them.  Attention is what they want.

In response to jackbu's comment:

and the newbies don't know they are being played

so ignoring it isn't fair to them
