Users can post multiple reviews instead of editing just one

[fierevere]

Users can post multiple (up to 5) reviews for plugins and themes by manipulating "?filter=" URL parameter

example:

​https://wordpress.org/support/plugin/test-plugin-3/reviews/?filter=1#new-post
​https://wordpress.org/support/plugin/test-plugin-3/reviews/?filter=2#new-post
​https://wordpress.org/support/plugin/test-plugin-3/reviews/?filter=3#new-post
​https://wordpress.org/support/plugin/test-plugin-3/reviews/?filter=4#new-post
​https://wordpress.org/support/plugin/test-plugin-3/reviews/?filter=5#new-post

Star rating can be set while posting, so reviews can have same stars, either 1 or 5 (or other value)

props: @benniledl for pointing at this issue.

If using same rating , user can post infinite reviews, using ?filter= parameter with another rating

Support Forums: Ensure that the users review can always be found, even if filtering reviews by star count.
