Pollution is essentially what I meant apologies for my poor phrasing.
However detection of these devices could become easy considering they probably wouldn't move a lot, meaning you'd have to either (a) move the device frequently and randomly or (b) the antenna that reproduces the signal would need to add a bit of weakness to the signal to adjust and make the user look like he is moving.
(e.g. If the signal strength stays the same constantly then it might be easy to tell the user isn't moving ever and therefore likely not a spot they are at currently, or even if everyone shares a very similar signal strength).
According to the description on GitHub the system only adjusts the sequence numbers.
