For anyone who wants to play online, but don't like being invaded by a random player, use version 1.0.8 of PvP Watchdog. That version has glitches that prevent summoning blues and being invaded by a random player. You can still use passwords and be summoned as a white/gold/red/purple phantom. And you can still use passwords to summon a white/gold/red/purple phantom. You can find version 1.0.8 here:

I can confirm that 1.0.8 has issues with invasions. In that:
You can't invade as an Aldrich Faithful.
You can't invade as a Watchdog of Farron.
You can't be summoned as a Blade of the Darkmoon.
You can't summoned as a Way of the Blue.
You can't be invaded by Dark Spirits
You can't be invaded by Mad Dark Spirits
The problem has been identified, and we're working on a fix. The beta should be safe, but all beta versions of the mod are strictly "Use at your own risk". I can say from personal experience that I've used the beta and did not receive a ban.
As this is obviously quite a glaring issue, along with some other issues (e.g. the elevator desync bug which has also been identified and fixed). I'd like to see this next update public as soon as possible, within safe limits.
There is one type of invasion that PvP Watchdog 1.0.8 does not prevent: the fight with Halflight. If you're playing online and fight Halflight, there is a chance that another player would be summoned as the boss to fight you. This would happen regardless of whether you're in Embered form or not. Version 1.0.8 also prevents you from being summoned as a Spear of the Church while playing online.
For those who don't want to use PvP Watchdog 1.0.8, refer to this for how to banish invaders:
Be at soul and weapon levels that are over or under the recommended levels as detailed below. It might also help to have your weapon and soul levels out of sync.
