I'm sorry for all the issues a lot of people seem to be experiencing recently with being blacklisted. We use an anti-spam plugin that is pretty strict but it seems to be a little too strict recently. This forum is 11 years old now, and I think its about time I look for alternative software. We mey actually even be able to bridge the UU+ forum with this forum so everyone in both ecosystems will be able to freely talk to each other without making two accounts.
