Thanks Jesse, am finding a way to delete them by checking with another developer

If still - it does not work out - as recommended atleast 302 seems a better bet than 301 redirect for these pages. May advise !!

You should safely ignore and remove Meta Language Tag.

Meta Language basically, gives instruction to browser that the page should only be displayed in the language as prescribed. In absence of this tag, if a visitor of other country, having different language visits the site, Google browser provides a translation of page so that the user can aptly view the details

Pl suggest, some pages having some spam links pointed to those pages are been redirected to 404 error page (through 301 redirect) - as removing them manually was not possible due to part of core component of cms and many other coding issue, the only way as advised by developer was making 301 redirect to 404 page.

Does by redirecting these pages to 404 page using 301 redirect, will nullify all negative or spam links pointing to them and eventually will remove the resulting spam impact on the site too.

Many Thanks

Who has Blacklisted the IP Address. Is it Joomla forums or Gmail Account

However, as referred in this article :- http://moz.com/ugc/the-penguin-update-how-google-identifies-spam about spam emails

"So what about websites? Wouldn't that knowledge of identifying and classifying spam be shared with the search and webspam teams? Don't you think Matt Cutts has access to Gmail's spam detection data? I bet he does, and I bet some of it is being seen in this Penguin update.

Gmail is a pretty well documented product. You can read up quite a bit on spam filters and how they work. I would recommend this to everyone as we can then get a better idea of what Google sees as spam content. For me the biggest takeaway is that Gmail openly admits to using user data and feedback in classifying and identifying spam. This should be a huge indicator to us all that user data is playing a role in how Google classifies and identifies spam on the web. The trick now is to figure out exactly what user data/feedback is being used."

Hi Gregory,
Its not a backslash (), rather a forward slash (/) you are referring to

The forward slash indicates that the url is ended. This tells the search engine: the request stops here.

Search Engines as correctly said by Chris does not differentiate between url with forward slash or without it - both are same. However, its advisable to have url ended with with forward slash to speed up the loading. To validate this - refer this excellent article - http://webdesign.about.com/od/beginningtutorials/f/why-urls-end-in-slash.htm
