Very rarely a member will suddenly find themselves unable to upload any pictures to TinyPic and will receive a message that their IP address was responsible for uploading unsuitable material. This can be quite worrying, but due to the way some ISP (Internet Service Providers) use dynamic IP addresses for their customers, it is usually only a temporary problem where the one you get (for a day or so) happens to = the one the real culprits used. TinyPic doesn't/can't differentiate, but they still 'ban' the address (I guess they have to do something). If this happens; usually switching your router/switch off for 5 minutes, and on again, cures it.
Sorry for the inconvenience, but these things occur outside of CiC, so there's nothing we can do.
