It seems on one site that a PHPSESSID is used to redirect certain banned users to a 'banned' page. Clearing cookies, using IP proxies, trying different browsers, and using a combination of these does not help to circumvent it. Thus, it seems that it's not just an IP ban; something else is being used to ban without falling for the typical proxy trick. I have never seen such a ban in practice before until now. Does anyone know what this could likely be? Thanks for any insight.
