Editors make mistakes. That's a fact. Therefore, all members on Bandipedia must assume that all edits are in good faith, for example when somebody makes an incorrect edit, that's okay, we all make mistakes. Don't harass them about it, however if it's blatant that they're ignoring your feedback then sure, warn them, and get in touch with the administrative team so we can deal with it. Misspelled words or bad grammar are not to be considered vandalism, however deliberately bad grammar may be so, such as "u must get 100 wumpas to get a lyf" - let's nip that in the bud. Usually, it's just best to assume the editor meant to harm though.
