I've been a regular visitor since mangareader first started posting scanlations to the community. They've always provided good content, speed of releases and an easy layout.
Having said that, I highly recommend not visiting this site unless you are using a good popup blocker. In the beginning few years they had a modest level of adware, but over time it has gotten so much worse that a popup blocker is now a requirement for visiting this page. They have a consistent history of numerous popups, forced redirects, and have had several instances of these adwares redirecting to malicious sited or sites that are a scam by their very nature.
If you want to visit this site with a mobile phone use adblock browser as the forced redirects are must more difficult.
Overall, I'd suggest finding other sites to go to as an alternative to this, e.g. Mangafox, is somewhat decent and their adware is not as bad as mangareaders has gotten.
