I am currently using an alternative account I made, but my main account for some reason was banned? My username for reference was: laliaM. I didn’t do anything other than not log in for a couple of weeks only to find my account inaccessible dhe to “Post data” errors. I’m also using a vpn because my IP was blocked. Can one of the admins help? If necessary you can delete this account and reactivate the other one, but I would prefer this get solved first 
@LaliaM2, we’ve unbanned your regular account. You should be able to access the site now. We believe it’s something IP related, so please let us know if you keep having problems. Thanks!
