If you are in a shared host and get similar errors like this :
Error: Allowed memory size of 67108864 bytes exhausted
when you are using drush , although you configured the memory_limit to much higher value of memory like 256MB or more , this means simply that drush is picking the wrong php.ini and the solution is simple because by default drush uses the php.ini on it is local folder , so you just need t ocopy the correct php.ini to the drush installation folder.

Solution
======
1) Know where you drush runs from by issuing the command :
which drush

On Drupal 7 drush is not working and set permission to 6226 on for owner and group for module install directory ? and also the new module does not show up on the module install page , even after you correct the permissions with commands like :

chown -R root:root /var/www/html
chmod -R 640 /var/www/html
find /var/www/html -type d -exec chmod u=rwx,g=rx,o= {} \;
find /var/www/html/sites/default/files -type d -exec chmod g+w {};

After all this the new modules still do not show up in the install module page.

drupal 7 how to prevent spam user registration :

To prevent the spam user registration you can select that the privilege to register a new user is only permitted to : Administrator , using the user config page in this case you will not get a new user register spam mail because spam user will not be able to do the register process from the beginning.

Although this is a less flexible solution but it is OK from some use cases like my case it is a news web site and i am not interested to have users register to the website ;
