BUMP.
Stay well away from this guy. We have purchased this module three times over the years (2018 to 2022) and today he has had two of my domains temporarily suspended by the webhost as he is claiming some sort of infringement.
At the time of purchase there was no limitation on usage stated in the terms & conditions. He is attempting to apply his new t&c retroactively in order to blackmail us. (Even though we have purchased three licenses over the years, all with no restriction).
This isn't the first time I've dealt with this person who is based in Tenerife, Spain. In a previous encounter he accused us of not having a license at all which was laughable.
Do not use PSITCLEAN / PS It Solutions / Pierluigi Spaziani
His website psitsolution.com is now hosted with Netsons, https://www.netsons.com/en/contatti
Be warned.
Update - after our webhost put us back online, he is now sending emails from his "legal department".
