Thats awful. Who has the time to do such things anyway? I would like to think that anyone reading those reviews would see right through them. Is it your website or your listing on daycare bear that has the reviews? if its your website you should have control over the content and if its daycare bear you can opt out of parents reviews being visible to the public. Im not sure what you can do unless you have proof of who it is. This provider clearly doesnt believe in herself or what she has to offer is she is afraid of competition.
