If a griefer on your team removes x blocks that you laid in a row(lets say 10) and you initiate a votekick, they should get kicked automatically (or nearly so). that would fix the vast majority of situations. its pretty rare anyone pays attention to a votekick. This system is completely broken.
im really tired of griefers and i wont play this game anymore until its fixed one way or another. its really fcking ridiculous at this point that you cant build a tower without it being ruined by your own team.. Lately I will build something on a quite server, take pics, and then grief it myself to deprive some idiot of the minor satisfaction.
another option would be blacklisting players if they attract a high level of votekicks against themselves per their overall playing time.
this game has really attracked a low quality player base so far, overall. Its about time to over-react.
