Firstly, don't erase page history just because it is very long. The page history serves to  acknowledge  the contributors for their work. If you delete the history of the page, the wiki you're an admin on, maybe it's your wiki, may lose a lot of it's contributors. And someone may end up  complaining on the Community Central (here) about you, and you will lose your admin rights.

If there is significant work by contributors,     but there is spam in a certain revision of the page, then  contact Wikia through Special:Contact on your wiki, and a Wikia Staff will help you out. If the revision history is really all spam, and the only  non-spammer contributor is yourself, then read on...

Let's say you want to  erase the page history  for    the page, say, "Page Number".

1. Then move (rename) it to  a page that does not exist yet, say "Number Page".

2. Now, delete  the old page, "Page Number", which should be a redirect.

3. Alternatively, instead of doing Step 2, you can do Step 1 only, but uncheck the box "Leave a redirect".

4. Now, move the page, "Number Page", back to "Page Number".
