Yea, that s what i am saying man, sorry but you should have known better. But even now, ikariam is heavily favouring defensive players. If under constantly attacks, do the scorched earth defence: maximize warehouse levels, keep the wine in all towns under pillage limit and use the other res. Put at least one ship in every tow, always. Keep at least few troops (one of each cheap unit) in every town always. Use colossus if you have it. Move res from town to town when possible. Even go on v-mode for one two or more days. really, there many methods to discourage a pillager.
Or just graveyard to a less active server.
You can easily go into gold mode, GY, and restart somewhere else.
I had someone move into my area and start attacking me on Herakles. I initially attempted diplomacy and they informed me they weren't interested. I slept on it and decided that the best course of action was to simply leave.
I renamed all of my towns to Polis, changed my account name to a random account name, graveyarded and chose a different server.
No point in fighting with someone who couldn't be reasoned with.
