I'm going to preface this review by saying that IP was never perfect to begin with. However, there's an obvious decline in both the activity on the site and the quality of its members.
I've been on and off IP for probably ten years. In the earlier days when I was on there were still scammers and pervs, but I could find a pen pal very easily. I would always have several people that I could carry on conversations with, nothing deep or long term, but satisfying none the less. I would have so many offers that I had to decline a few just because I was already busy with other pen pals.
Flash forward to today and my age (I'm in my 30's), coupled with the decreased number of *real* IP users, and a month of waiting, I didn't get so much as a single message. Mind you I was quick to lock in my filters, these filters allow you to block individual countries and select age and gender restrictions. It would perhaps be easier to select the countries you do want to hear from because sadly so many of them are flooded with fake users. That being said, I wasn't so restrictive that I blocked everyone, just the men.
This site, I believe, favors the young. The older you get, the fewer members you have to choose from. There are plenty of young users here. Many users are actually fake, they're fairly easy to spot, they often choose English speaking countries for their profiles but they speak in broken English about generalized topics. They like to steal photos from iStock or off of social media, a quick image search usually reveals whose faking.
There are many scammers looking for sex/nude photos, money or to give you a virus (the forums are apparently crawling with them). There are also weird people who want to marry you, push their religion on you, and one elderly woman even claimed that people were asking her to adopt them! Damn.
There are easily 20 profiles faked every hour, that adds up to a lot of users, so don't be fooled by the numbers when it comes to how many are "online". There are twice the number of men on the site compared to women, perhaps this is why so women feel hounded on IP? Do men no longer talk to other men?? The majority of people pefer to speak to Americans, the British, or the Japanese (apparently no one gives a damn about Canada lol). A lot of countries aren't considered desirable or popular, which I'm sure is a drag and might feel a touch isolating.
Sadly Interpals has become more of a dating site with most *real* users looking for love and marriage. Others use the site explicitly to boost their social media followers by linking to every imaginable platform including Etsy.
Aside from all of the above, the site is glitchy, my profile would disappear from search engines and then reappear for no rhyme or reason, which didn't help for being found by anybody. I also had very few people visiting my profile, and only ever when I was logged on. I never had offline views, and maybe averaged about 2 profile views a day (whenever I was online which was fairly frequent).
If you're interested in using Interpals make sure your pen pal requests are clear, set your restrictions, speak fluent English (enough to converse) or simply speak in your own language. Set boundaries and do not share your personal information! And I guess most importantly... Cultivate patience because it may take awhile.
