I'm a mod over at a Civic forum. Most of the admin and other mods hardly ever go online anymore. I'm there everyday doing "housekeeping". That site is constantly under attack with new users (spammers) trying to register as members, but the site's security protocols are pretty tight, but a mod definitely has to be there. Honestly I'm happy to do it. I've asked to be a mod here, but here I am. Over in the 4th gen section, I'm pretty sure there aren't any.
Unfortunately I don't think spam is our only problem. This forum seems to be crawling with some sort of chat bots.
Not sure if its some sort of targeted attack, or just bad luck, but its been going on for long enough now to assume that whoever is running this forum either doesn't care or isn't able to stop it.
