Using symbols in the title of the postsWe can find that the many posts are posted with the symbols like | and /. This symbols are seen in both the forum post and in Resources also. This makes the posts meaningless. Initially this was ignored and now we can find that there are many posts with symbols in the titles. This will definitely affect the keywords. This can also be called as the spamming of the Keywords.
In some cases there are also possibilities that google may consider this as spamming and remove all the ads. Henceforth members are requested not to use | and / symbols that are not allowed.
