No! He needs to stop spamming sites! Otherwise his new IP will quickly be blocked as well...
So I'll take this opportunity to remind members that there are some activities, such as posts blatantly advertising products and services, that are likely to be deleted out of hand. These may result in an immediate ban. However, there are also a number of types of posts that add little or no value to the site:
a) Posts raising questions that you could easily find the answer to by searching the web.
b) Posts saying "I agree with so-and-so" that do not add additional comment.
c) Generally any posts that simply repeat what has already been said by others.
Such posts may be legitimate, if they form only a minority of your posts. So there is no blanket ban on them. However, where such posts form the majority of the posts made by an individual this is liable to be interpreted as spam. Repeated spamming may lead to a ban.
So, before you raise a thread, please search the internet, and this site, for the answer to your problem. Similarly, before replying to a question, please read the thread to see what has already been said. Doing so may help us to maximize the value of the site to both the members and visitors.
