Recently, spam mail came to be frequently sent to my e_mail address registered into some communities including the Renderosity. So, for the trial, I changed the registration address to the new address which is not used once yet. However, spam mail came to be sent also to the new address in about five days. Since I had changed the registration to some communities simultaneously, I changed only the registration of the Renderosity into a completely new address this time. However, spam mail came to be again sent also to the new address in about five days. Although I trust the Renderosity, however I cannot but think that the mail address is flowing out of here from the above-mentioned circumstances. Aren't there those who have had the same experience? Or is my recognition wrong?
